产品详情
* 以下信息仅供参考，详情请以原厂网站为准

  • 产品名称:Fluorescein Maleimide, 12 mg

    别名:荧光素标记的马来酰亚胺

    产品描述:

    Fluorescein Maleimide is designed for fluoresceinating proteins, nucleic acids or other molecules containing one or more thiol groups. Molecules to be labeled with Fluorescein Maleimide require free thiol groups. In the case of proteins, Fluorescein Maleimide will react with exposed cysteine residues. Alternatively, free thiols may be generated by reducing disulfide bonds or by modifying other reactive groups such as primary amines with compounds like Traut’s reagent (2-iminothiolane).For labeling nucleic acids, thiols can be introduced into DNA, RNA, or oligonucleotides using the FastTag®, 5′ EndTag™ or 3′ EndTag™ nucleic acid labeling systems.This fluorescent label can be directly detected or used as a hapten and detected with our high affinity antibody reagents.

Succinylated Wheat Germ Agglutinin (WGA), Agarose bound, 5 ml

产品货号：AL-1023S-5

规格：5 ml

产品详情

产品名称:Succinylated Wheat Germ Agglutinin (WGA), Agarose bound, 5 ml

别名:琥珀酰化小麦胚芽凝集素，琼脂糖交联

产品描述:

Wheat germ agglutinin (WGA) succinylated has been reported to have properties distinct from the native lectin. Evidence suggests that Succinylated Wheat Germ agglutinin does not bind to sialic acid residues, unlike the native form, but retains its specificity toward N-acetylglucosamine. Using conjugates of the native lectin and the succinylated form can provide a system to distinguish between sialylated glycoconjugates and those containing only N-acetylglucosamine structures.Agarose bound*, succinylated WGA is prepared using our affinity-purified lectins. Heat stable, cross-linked 4% agarose beads with a molecular weight exclusion limit of about 2×107 daltons are used as the solid-phase matrix to which the lectins are covalently coupled. The attachment of the lectins to the beads is carefully controlled to preserve lectin activity and minimize conformational changes of the bound lectins that might result in nonspecific ionic or hydrophobic interactions. The technique we have developed to couple lectins to agarose beads inserts a hydrophilic spacer arm between the lectin and the matrix.This coupling method provides several advantages over the traditional cyanogen bromide procedure:Maximum carbohydrate binding activity of the coupled lectins is retainedLinkage is stable over a range of pH valuesConjugated proteins are not leached off the beads by Tris or other routinely used buffersNo residual charges are present after conjugation. This minimizes non-specific binding to the matrix.Our agarose bound lectins are supplied at a constant concentration of lectin per ml of settled beads. The concentration for each lectin is selected to achieve the highest glycoconjugate binding capacity per mg of lectin present in the beads. Each lot is tested for its binding capacity using glycoproteins known to bind the lectin. This provides a guideline for the user and assures the quality of our agarose bound lectins.Inhibiting/Eluting Sugar: Chitin Hydrolysate (Cat. No. SP-0090) or 500 mM N-acetylglucosamine with salt and/or acid elution generally required*3 mg lectin/ml gel

据报道，琥珀酰化的小麦胚芽凝集素 (WGA) 具有不同于天然凝集素的特性。有证据表明，与天然形式不同，琥珀酰化小麦胚芽凝集素不与唾液酸残基结合，但保留了其对 N-乙酰氨基葡萄糖的特异性。使用天然凝集素和琥珀酰化形式的缀合物可以提供一个系统来区分唾液酸化糖缀合物和仅含有 N-乙酰氨基葡萄糖结构的糖缀合物。琼脂糖结合*，琥珀酰化 WGA 是使用我们的亲和纯化凝集素制备的。具有约 2×107 道尔顿分子量排除极限的热稳定、交联的 4% 琼脂糖珠用作凝集素共价偶联的固相基质。凝集素与珠子的连接受到仔细控制，以保持凝集素活性并最大限度地减少可能导致非特异性离子或疏水相互作用的结合凝集素的构象变化。我们开发的将凝集素与琼脂糖珠偶联的技术在凝集素和基质之间插入了一个亲水性间隔臂。这种偶联方法与传统的溴化氰方法相比具有几个优点：保持偶联凝集素的最大碳水化合物结合活性pH 值范围 结合的蛋白质不会被 Tris 或其他常规使用的缓冲液从珠子上浸出 结合后不存在残留电荷。这最大限度地减少了与基质的非特异性结合。我们的琼脂糖结合凝集素以每毫升沉降珠子的恒定凝集素浓度提供。选择每种凝集素的浓度以实现珠中每毫克凝集素的最高糖缀合物结合能力。使用已知结合凝集素的糖蛋白测试每批的结合能力。这为用户提供了指导并确保了我们琼脂糖结合凝集素的质量。抑制/洗脱糖：甲壳素水解物（货号 SP-0090）或 500 mM N-乙酰氨基葡萄糖，通常需要盐和/或酸洗脱*3毫克凝集素/毫升凝胶

实验应用:Glycobiology,Affinity Chromatography

推荐稀释度:

Wash gel thoroughly with buffer before use to remove sugar added to stabilize the lectin. Recommended product for eluting glycoconjugates bound to this agarose-lectin: Glycoprotein Eluting solution, Cat. No. ES-5100. Alternatively, 0.5 M N-Acetyl-D-Glucosamine (GlcNAc) can be used.For those glycoconjugates having very high affinity for WGA, it may be necessary to lower the pH of the eluting sugar solution to pH 3.0 with acetic acid and increase the concentration of GlcNAc. After use, wash the gel with several column volumes of buffered saline, then resuspend gel in buffered saline containing 0.08% sodium azide for storage.

使用前用缓冲液彻底清洗凝胶，以去除为稳定凝集素而添加的糖。 用于洗脱与该琼脂糖凝集素结合的糖缀合物的推荐产品：糖蛋白洗脱溶液，Cat. 编号 ES-5100。 或者，可以使用 0.5 M N-乙酰基-D-氨基葡萄糖 (GlcNAc)。对于那些对 WGA 具有非常高亲和力的糖缀合物，可能需要用乙酸将洗脱糖溶液的 pH 值降低到 3.0 并增加 GlcNAc 的浓度。 使用后，用几柱体积的缓冲盐水清洗凝胶，然后将凝胶重悬于含有 0.08% 叠氮化钠的缓冲盐水中保存。

产品详情

产品名称:Peanut Agglutinin (PNA), CY®3, 1 mg

别名:花生凝集素，Cy3标记

产品描述:

Cy3 PEANUT AGGLUTININ PNA binds preferentially to the T-antigen, a galactosyl (β-1,3) N-acetylgalactosamine structure present in many glycoconjugates such as M and N blood groups, gangliosides, and many other soluble and membrane-associated glycoproteins and glycolipids. With certain exceptions, the receptor sequence for PNA is normally sialylated which prevents the lectin from binding to its receptor oligosaccharide (see Jacalin). Even sialic acid which is not bound directly to the receptor sugars may inhibit binding. The presence of calcium ions in diluents can enhance the binding of PNA to receptors, possibly by neutralizing the negative charges on sialic acid residues adjacent to the receptor sequence.Cy3 labeled Peanut agglutinin has an appropriate number of fluorochromes bound to provide the optimum staining characteristics for this lectin. This conjugate is supplied essentially free of unconjugated fluorochromes.Excitation: 550 nmEmission: 570 nmColor: Red

  • 产品名称:
    Peanut Agglutinin (PNA), Agarose bound, 2 ml
  • 别名:
    花生凝集素，琼脂糖交联
  • 产品描述:
    Peanut agglutinin (PNA) binds preferentially to the T-antigen, a galactosyl (β-1,3) N-acetylgalactosamine structure present in many glycoconjugates such as M and N blood groups, gangliosides, and many other soluble and membrane-associated glycoproteins and glycolipids. With certain exceptions, the receptor sequence for PNA is normally sialylated which prevents the lectin from binding to its receptor oligosaccharide (see Jacalin). Even sialic acid which is not bound directly to the receptor sugars may inhibit binding. The presence of calcium ions in diluents can enhance the binding of PNA to receptors, possibly by neutralizing the negative charges on sialic acid residues adjacent to the receptor sequence.PNA is useful in distinguishing between normal and tumor tissues and in assessing malignancy in transitional mucosa. In addition, PNA binding can be used to measure cellular maturity in lymphoid tissues, to distinguish a variety of lymphocyte subpopulations in man and experimental animals, and to measure the levels of lymphoid cell populations in many diseases. PNA can be employed in the fractionation of stem cells in mice for use in bone marrow transplantation across histocompatibility barriers.A major cell surface receptor for PNA may be asialo GM1 ganglioside. Since PNA shares specificity with the antibody to this glycolipid, PNA and the antibody can be used interchangeably in some applications.Agarose bound* PNA is prepared using our affinity-purified lectins. Heat stable, cross-linked 4% agarose beads with a molecular weight exclusion limit of about 2×107 daltons are used as the solid-phase matrix to which the lectins are covalently coupled. The attachment of the lectins to the beads is carefully controlled to preserve lectin activity and minimize conformational changes of the bound lectins that might result in nonspecific ionic or hydrophobic interactions. The technique we have developed to couple lectins to agarose beads inserts a hydrophilic spacer arm between the lectin and the matrix.This coupling method provides several advantages over the traditional cyanogen bromide procedure:Maximum carbohydrate binding activity of the coupled lectins is retainedLinkage is stable over a range of pH valuesConjugated proteins are not leached off the beads by Tris or other routinely used buffersNo residual charges are present after conjugation. This minimizes non-specific binding to the matrix.Our agarose bound lectins are supplied at a constant concentration of lectin per ml of settled beads. The concentration for each lectin is selected to achieve the highest glycoconjugate binding capacity per mg of lectin present in the beads. Each lot is tested for its binding capacity using glycoproteins known to bind the lectin. This provides a guideline for the user and assures the quality of our agarose bound lectins.Inhibiting/Eluting Sugar: 200 mM galactose*5 mg lectin/ml gel

  • 花生凝集素 (PNA) 优先与 T 抗原结合，这是一种半乳糖基 (β-1,3) N-乙酰半乳糖胺结构，存在于许多糖缀合物中，例如 M 和 N 血型、神经节苷脂和许多其他可溶性和膜相关糖蛋白和糖脂。除了某些例外，PNA 的受体序列通常是唾液酸化的，这会阻止凝集素与其受体寡糖结合（参见 Jacalin）。甚至不直接与受体糖结合的唾液酸也可能抑制结合。稀释剂中钙离子的存在可以增强 PNA 与受体的结合，可能通过中和受体序列附近唾液酸残基上的负电荷。PNA 可用于区分正常组织和肿瘤组织以及评估移行黏膜的恶性肿瘤。此外，PNA 结合可用于测量淋巴组织中的细胞成熟度，区分人和实验动物中的各种淋巴细胞亚群，以及测量许多疾病中淋巴细胞群的水平。 PNA 可用于分离小鼠干细胞，用于跨越组织相容性障碍的骨髓移植。PNA 的主要细胞表面受体可能是去唾液酸 GM1 神经节苷脂。由于 PNA 与针对这种糖脂的抗体具有特异性，因此 PNA 和抗体可以在某些应用中互换使用。琼脂糖结合* PNA 是使用我们的亲和纯化凝集素制备的。具有约 2×107 道尔顿分子量排除极限的热稳定、交联的 4% 琼脂糖珠用作凝集素共价偶联的固相基质。凝集素与珠子的连接受到仔细控制，以保持凝集素活性并最大限度地减少可能导致非特异性离子或疏水相互作用的结合凝集素的构象变化。我们开发的将凝集素与琼脂糖珠偶联的技术在凝集素和基质之间插入了一个亲水性间隔臂。这种偶联方法与传统的溴化氰方法相比具有几个优点：保持偶联凝集素的最大碳水化合物结合活性pH 值范围 结合的蛋白质不会被 Tris 或其他常规使用的缓冲液从珠子上浸出 结合后不存在残留电荷。这最大限度地减少了与基质的非特异性结合。我们的琼脂糖结合凝集素以每毫升沉降珠子的恒定凝集素浓度提供。选择每种凝集素的浓度以实现珠中每毫克凝集素的最高糖缀合物结合能力。使用已知结合凝集素的糖蛋白测试每批的结合能力。这为用户提供了指导并确保了我们琼脂糖结合凝集素的质量。抑制/洗脱糖：200 mM 半乳糖*5 mg 凝集素/ml 凝胶
