产品介绍    background:
CD57 recognizes a (Mr 100-110kDa) oligosaccharide antigenic determinant on myeloid cells and on a variety of polypeptides, lipids and chondroitan sulfate proteoglycans. This surface antigen is associated with myelin-associated glycoprotein (MAG). The CD57 antigen is present on 15-20% of normal peripheral blood mononuclear cells. It is expressed on a subset of natural killer cells (60%) and on a subset of T-lymphocytes. This carbohydrate is also present on N-CAM in the nervous system.

Function:
Involved in the biosynthesis of L2/HNK-1 carbohydrate epitope on glycoproteins. Can also play a role in glycosaminoglycan biosynthesis. Substrates include asialo-orosomucoid (ASOR), asialo-fetuin, and asialo-neural cell adhesion molecule. Requires sphingomyelin for activity: stearoyl-sphingomyelin was the most effective, followed by palmitoyl-sphingomyelin and lignoceroyl-sphingomyelin. Activity was demonstrated only for sphingomyelin with a saturated fatty acid and not for that with an unsaturated fatty acid, regardless of the length of the acyl group.

Subunit:
Homodimer (Potential).

Subcellular Location:
Golgi apparatus membrane; Single-pass type II membrane protein.

Tissue Specificity:
Mainly expressed in the brain.

Similarity:
Belongs to the glycosyltransferase 43 family.

单抗的制备过程：
1.动物免疫：注射特定抗原蛋白
2.分离脾淋巴细胞：与培养好的骨髓瘤细胞混合，人工诱导细胞融合。
3.细胞融合：淋巴细胞杂交瘤的制备
4.杂交瘤细胞的筛选：HAT选择培养基筛选出杂交瘤细胞。
5.培养杂交瘤细胞：体外培养杂交瘤细胞，从培养液中分离提取单克隆抗体。或者，将杂交瘤细胞移植到小鼠腹腔内，从小鼠腹水中分离提取单克隆抗体。
6.单克隆抗体的制备和冻存、纯化
