| 产品描述 概述Recombinant Human Serine Protease Inhibitor-clade B3 is produced by our E.coli expression system and the target gene encoding Met1-Pro390 is expressed with a 6His tag at the N-terminus. 使用说明This material is offered by Novin Biotech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE. 技术规格| Tag | N-6His |  | 种属 | Human |  | 表达系统 | E.coli |  | Accession# | P29508 |  | Source | E.coli |  | Formulation_Description | Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. |  | Storage | Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months. |  | Reconstitution | Dissolve the lyophilized protein in distilled water. |  | Purity | Greater than 95% as determined by reducing SDS-PAGE. |  | Endotoxin | Less than 0.1 ng/μg (1 EU/μg) as determined by LAL test. |  | Background | Serpin B3, also known as squamous cell carcinoma antigen-1 (SCCA-1), is a member of the serpin superfamily of serine protease inhibitors. Serpin B3 belongs to the subgroup ovalbumin-related serpins which are involved in the regulation of apoptosis, inflammation, angiogenesis and embryogenesis. It may act as a papain-like cysteine protease inhibitor to modulate the host immune response against tumor cells. It also functions as an inhibitor of UV-induced apoptosis via suppression of the activity of c-Jun NH(2)-terminal kinase (JNK1). |
