为了建立新的非放射性基因标记和检测体系,用化学方法合成了Fmoc-苯丙氨酰氨基己酸。然后将其作为半抗原,与载体蛋白偶联(通过EDC),用于免疫BALB/c小鼠。取脾细胞与Sp2/0小鼠骨髓瘤细胞融合。经ELISA筛选及有限稀释法克隆化,选出一株阳性克隆,分泌专一性抗Fmoc-苯丙氨酰氨基己酸的抗体。用双抗体夹心法测得其亚类为IgG1。用间接ELISA法测得腹水效价为1.6×10-5。用竞争性ELISA法测得亲和常数为3.6×106M-1。
In order to establish a new non-radioactive gene marker and detection system, Fmoc-phenylalanyl aminocaproic acid was chemically synthesized. This was then used as a hapten, coupled to the carrier protein (via EDC) for immunization of BALB / c mice. Spleen cells were spliced to Sp2 / 0 mouse myeloma cells. After screening by ELISA and limiting dilution, a positive clone was selected to secrete specific anti-Fmoc-phenylalanyl amino caproic acid antibody. Its subclass was IgG1 measured by double antibody sandwich method. Ascites titer measured by indirect ELISA was 1.6 × 10-5. The affinity constant was 3.6 × 10 6 M -1 by competitive ELISA.
