背景介绍
RBP4 (retinol-binding protein 4) is a carrier protein that transports vitamin A (retinol) from the liver to the peripheral tissues. Synthesized primarily by hepatocytes and adipocytes as a 21 kDa non-glycosylated protein, RBP4 is secreted into the circulation as a retinol-RBP4 complex. In plasma the RBP4-retinol complex is bound to transthyretin (TRR), which prevents prevent kidney filtration. Two truncated forms of RBP4, RBP4-L (truncated at Leu-183) and RBP4-LL (truncated at Leu-182 and Leu-183), exist by proteolytic process. RBP4-L and RBP4-LL, which do not bind TTR, are normally excreted into the urine but accumulate in the serum during renal failure. Urinary RBP4 has been reported as marker for glomerular disease. RBP4 also was identified as an adipokine that elevated in some INS-resistant states. Measurement of serum RBP4 could be used to assess the risk of INS resistance, type 2 diabetes, obesity, and cardiovascular disease. (18752671, 16034410)

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。
