BSSP-4 Protein, Human, Recombinant (His)

产品编号 TMPJ-01320BSSP-4 Protein, Human, Recombinant (His)

Brain-Specific Serine Protease 4 (BSSP-4) is a serine protease that preferentially cleaves the synthetic substrate H-D-Leu-Thr-Arg-pNA compared to tosyl-Gly-Pro-Arg-pNA. BSSP-4 is expressed abundantly in the epithelial cells of the airways, including trachea, esophagus and fetal lung, but scarce in adult lung and expressed at low levels in placenta, pancreas, prostate and thyroid gland. BSSP-4 belongs to the peptidase S1 family and related to trypsin, referentially hydrolyzing substrates after arginine and lysine residues. However, BSSP-4 is less susceptible to inhibition by common trypsin inhibitors such as aprotinin, α1-antitrypsin and secretory leukocyte protease inhibitor. BSSP-4 efficiently converts pro-urokinase- type plasminogen activator to its mature, active form.

实验操作小课堂
常见问题解答
产品溶解需要超声吗?如果没有超声仪怎么办?
超声可以加快粉末的溶解速度,如果您的化合物溶解不了,建议您尝试超声。如果您没有超声仪,建议您选择较低母液浓度,或者较少粉末量,尝试溶解。
收到化合物后,是否需要称量后配制储备液?
对于小包装,如 1 mg、5 mg、10 mg 等,不建议二次称量。这样会导致化合物损耗,且无法估算。TargetMol 所有产品原装进口,精准称量,您收到后可直接添加相应量溶剂。 对于大包装,如果您需要分批次实验,可每次称量后配制储备液,建议您 10 mg 起称,称量的误差会小一些;当然条件允许,也可以先配制成高浓度母液,分装备用。
加药后检测结果没有作用,是不是产品质量有问题?
产品质量没有问题,都是经过两次严格质检的,HNMR确定产品结构,HPLC确定化合物纯度。同一个抑制剂由于实验材料(细胞、动物)的不同,IC50 和实验效果也是不一样的,不能照搬文献报道的方法,应该根据自己的实验设立浓度梯度,得到一个最适合的浓度。
动物不能耐受 DMSO,给药时 DMSO量应该如何控制?
对于普通的老鼠,DMSO 的浓度应控制在 10% 以下,对于裸鼠、转基因小鼠、耐受性弱的老鼠等,DMSO 浓度需控制在2%以下。对于首次操作的抑制剂,建议先做溶剂阴性对照,确认溶解对动物无非特异性影响。
动物实验常用溶解方法?
首先,您需要确认给药剂量、给药方式。对于具体的产品,优先找引用我们产品的文献里的使用方法,再找其他文献里的配方。 如果没有相关的文献,且该化合物的 DMSO 溶解度比较好,我们推荐通用配方: 10% DMSO+40% PEG300+5% Tween-80+45% Saline/PBS/ddH2O。溶剂依次加入,尽量溶解后再加入下一个溶剂。正常鼠建议 DMSO 浓度在 10% 以下,裸鼠体弱鼠等配方的 DMSO 浓度建议在 2% 以下,根据溶液是否澄清,助溶剂 PEG300、Tween-80 的比例可以适当调整。如果有其他助溶剂也可以使用。 以上配方仅供参考,体内配方并不是绝对的,需要根据不同情况进行调整。建议先取少量化合物测试配方,再进行大量配制。配完也可以再使用超声、加热等方式助溶,看看能不能澄清一点。 腹腔注射对粉末的溶解度要求比较高,建议购买盐形式化合物。如果给药剂量比较大,也有报道使用混悬液进行腹腔给药的。 对于灌胃给药,且剂量比较大的情况下,建议用 0.5% CMC-Na 配置成均匀混悬液进行给药。
