背景介绍
CD146, also known as melanoma cell adhesion molecule (MCAM) or MUC18, originally identified as a biomarker of melanoma progression, is a transmembrane glycoprotein of 113-130 kDa, belonging to the immunoglobulin (Ig) superfamily (PMID: 8378324; 25993332). Structurally, it consists of five Ig domains, a transmembrane domain, and a cytoplasmic region. In normal adult tissue, CD146 is primarily expressed by vascular endothelium and smooth muscle. CD146 is a key cell adhesion protein in vascular endothelial cell activity and angiogenesis, and has been used as marker of circulating endothelium cells (CECs) (PMID: 19356677). In addition to the membrane-anchored form of CD146, a soluble form of CD146 (sCD146, 105 kDa) has also been found in human plasma and in the supernatant of cultured human endothelial cells (PMID: 9462829; 19229070; 16374253; 14597988). This antibody detects a band at approximately 120 kDa that corresponds to the molecular weight of glycosylated CD146. Treatment of lysates of HepG2 cells and L02 cells with PNGase F, which removes oligosaccharides from N-linked glycoproteins, led to a down-shift of the detected band.

文献和实验1. 杂交瘤阳性克隆的筛选与克隆化 在HAT培养基中生长的杂交瘤细胞，只有少数是分泌预定特异性单克隆抗体的细胞，因此，必须进行筛选和克隆化。通常采用有限稀释法进行杂交瘤细胞的克隆化培养。采用灵敏、快速、特异的免疫学方法，筛选出能产生所需单克隆抗体的阳性杂交瘤细胞，并进行克隆扩增。经过全面鉴定其所分泌单克隆抗体的免疫球蛋白类型、亚类、特异性、亲和力、识别抗原的表位及其分子量后，及时进行冻存。2. 单克隆抗体的大量制备 单克隆抗体的大量制备重要采用动物体内诱生法和体外培养法。
