產(chǎn)品介紹    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.

單抗的制備過程：
1.動物免疫：注射特定抗原蛋白
2.分離脾淋巴細胞：與培養(yǎng)好的骨髓瘤細胞混合，人工誘導細胞融合。
3.細胞融合：淋巴細胞雜交瘤的制備
4.雜交瘤細胞的篩選：HAT選擇培養(yǎng)基篩選出雜交瘤細胞。
5.培養(yǎng)雜交瘤細胞：體外培養(yǎng)雜交瘤細胞，從培養(yǎng)液中分離提取單克隆抗體。或者，將雜交瘤細胞移植到小鼠腹腔內，從小鼠腹水中分離提取單克隆抗體。
6.單克隆抗體的制備和凍存、純化
