整合素样金属蛋白酶与凝血酶9型抗体产品介绍 ADAMTS proteases are secreted enzymes containing a prometalloprotease domain of the reprolysin type. The ADAMTS proteases function in processing of procollagens and von Willebrand factor as well as catabolism of aggrecan, versican and brevican. They have been demonstrated to have important roles in connective tissue organization, coagulation, inflammation, arthritis, angiogenesis and cell migration. ADAMTS9 is closest in homology to ADAMTS20, sharing 54% overall identity, and like ADAMTS20 ADAMTS9 gas a GON like domain at the carboxyterminal end. The GON domain at the carboxyterminal end is similar to the GON1 protein in C. elegans, mutations of which lead to defective gonadal development. ADAMTS9 is expressed in ovary and testis, but little is known about the role of ADAMTS9 in reproductive organs. ADAMTS9 is also expressed in the heart, placenta, lung, skeletal tissue, and pancreas, so the protein must have wider functions than just gonadal development. ADAMTS9, like ADAMTS20, has a total of 15 thrombospondin like domains. The first TS domain begins shortly after the catalytic and disintegrin domains. TS domains 2 to 6 follow a spacer domain, followed by linker domain 1, then TS domains 7 & 8, linker domain 2, and then TS domains 9 to 15. In other ADAMTS proteins the TS motifs are thought to bind to the ECM. The ADAMTS proteins contain at least one prohormone convertase cleavage site, although it appears that one site is used preferentially, and cleavage of the propeptide domain at this site generates active enzymes. For ADAMTS9, this site is the RRTKR sequence, and the mature ADAMTS9 has an aminoterminal sequence of FLSYPR. The catalytic site of ADAMTS9 is most like ADAMTS1, 14 and 15, with an HExxHVFNMxH sequence, perhaps giving these enzymes some shared specificity.

纯度:在实验的任何阶段,确定抗体溶液纯度的最简单方法是取一部分样本进行SDS-PAGE电泳。凝胶可用考马斯亮蓝染色(灵敏度为0.1—0.5ug/带)或银染(灵敏度1~l0ug/带)。
定量:如果抗体还不纯,有一个快捷的定量方法,即通过SDS-PAGE电泳分离出轻、重链,然后和已知的标准染色带比较。如果需要分析许多样本,用免疫测定法对抗体定量较容易。如果抗体是经过纯化的,可通过测蛋白总量代替上述两种方法,有一简单的方法,即紫外吸收法。整合素样金属蛋白酶与凝血酶9型抗体的量可通过测280nm处的吸收值来测(10D大致相当于0.75mg/m1的纯化抗体)。
抗原结合活性:一般说来,纯化方法不会引起抗原结合活性的改变。用蛋白G或蛋白A树脂很少导致抗体活性丧失。然而,如果最终抗体产物的作用不如原来所预料的好,检测抗体纯化过程所丢失的活性就极为重要。用一系列滴定法比较纯化的抗体和其原材料的活性,以标定每一步中的总抗体量,这将有助于较好的估计通过纯化所丢失的活性。
