應用
来自Sigma的酶已被用于开发均相时间分辨荧光（HTRF）检测法，以用于以小型化的高通量筛选形式测定羧肽酶B活性。它已被用于评估C-末端赖氨酸在人纤溶酶原结合至双歧杆菌过程中的影响。使用流式细胞术对用羧肽酶B（一种C-末端赖氨酸特异性内肽酶）处理的效果进行分析和检测。
羧肽酶B已被用于开发用于圈养和野生北极熊的非侵入性妊娠试验。羧肽酶B已被用于确定急性胰腺炎的新潜在生物标志物。
生化／生理作用
羧肽酶B是一种蛋白水解酶，能够快速水解肽键，从而从肽和蛋白质中释放某些羧基末端碱性氨基酸。其分子量为34,300±600 Da。其每摩尔含有一克不可透析的锌原子。金属螯合剂1,10-菲咯啉、8-羟基喹啉-5-磺酸、和2,2′-联吡啶可抑制该酶活性。
包裝

An epitope-unmasking, homogeneous time-resolved fluorescence (HTRF) assay has been developed for measuring carboxypeptidase B (CPB) activity in a miniaturized high-throughput screening format. The enzyme substrate (biotin-RYRGLMVGGVVR-OH) is cleaved by CPB at the C terminus, causing release of the C-terminal Arg
