粘蛋白/岩藻糖基转移酶3抗体产品介绍 Glycosyltransferases that mediate the regio- and stereoselective transfer of sugars, such as the fucosyltransferases, determine cell surface-carbohydrate profiles, which is an essential interface for biological recognition processes. Fucosyltransferases catalyze the covalent association of fucose to different positional linkages in sugar acceptor molecules. The carbohydrate moieties generated and covalently attached to cell surfaces are necessary to ensure a surface contour that satisfies physiological roles, which are reliant on adhesion molecules such as Selectins (1-3). Hematopoietic lineages rely on Fucosyltransferases to confer a surface carbohydrate phenotype, which mediates proper cell adhesion molecule recruitment and cell trafficking (4-6). Blood Group Lewis b is a carbohydrate determinant carried on both glycolipids and glycoproteins.

Function : Blood group Lewis b is a carbohydrate determinant carried on both glycolipids and glycoproteins, detected on erythrocytes, certain epithelial cells, and in secretions of certain individuals.

Subcellular Location : Plasma membrane - adsorbed onto the surface of erythrocytes.

Tissue Specificity : Highly expressed in stomach, colon, smallintestine, lung and kidney and to a lesser extent in salivarygland, bladder, uterus and liver.

Similarity : Belongs to the glycosyltransferase 10 family.

Database links : UniProtKB/Swiss-Prot: P21217.1

在纯化抗体时需要控制好几个指标，包括纯度、含量及抗体的抗原结合活性。

纯度：在实验的任何阶段，确定抗体溶液纯度的最简单方法是取一部分样本进行SDS-PAGE电泳。凝胶可用考马斯亮蓝染色(灵敏度为0.1—0.5ug/带)或银染(灵敏度1～l0ug/带)。

定量：如果抗体还不纯，有一个快捷的定量方法，即通过SDS-PAGE电泳分离出轻、重链，然后和已知的标准染色带比较。如果需要分析许多样本，用免疫测定法对抗体定量较容易。如果抗体是经过纯化的，可通过测蛋白总量代替上述两种方法，有一简单的方法，即紫外吸收法。粘蛋白/岩藻糖基转移酶3抗体的量可通过测280nm处的吸收值来测(10D大致相当于0.75mg/m1的纯化抗体)。

抗原结合活性：一般说来，纯化方法不会引起抗原结合活性的改变。用蛋白G或蛋白A树脂很少导致抗体活性丧失。然而，如果最终抗体产物的作用不如原来所预料的好，检测抗体纯化过程所丢失的活性就极为重要。用一系列滴定法比较纯化的抗体和其原材料的活性，以标定每一步中的总抗体量，这将有助于较好的估计通过纯化所丢失的活性。
