Alpha-1-antiproteinase (Serpina1), rat, recombinant

Organism: Rattus norvegicus (Rat). Source: E.coli. Expression Region: 25-411aa. Protein Length: Full Length of Mature Protein. Tag Info: N-terminal 6xHis-SUMO-tagged. Target Protein Sequence: EDAQETDTSQ QDQSPTYRKI SSNLADFAFS LYRELVHQSN TSNIFFSPMS ITTAFAMLSL GSKGDTRKQI LEGLEFNLTQ IPEADIHKAF HHLLQTLNRP DSELQLNTGN GLFVNKNLKL VEKFLEEVKN NYHSEAFSVN FADSEEAKKV INDYVEKGTQ GKIVDLMKQL DEDTVFALVN YIFFKGKWKR PFNPEHTRDA DFHVDKSTTV KVPMMNRLGM FDMHYCSTLS SWVLMMDYLG NATAIFLLPD DGKMQHLEQT LTKDLISRFL LNRQTRSAIL YFPKLSISGT YNLKTLLSSL GITRVFNNDA DLSGITEDAP LKLSQAVHKA VLTLDERGTE AAGATVVEAV PMSLPPQVKF DHPFIFMIVE SETQSPLFVG KVIDPTR. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Inhibitor of serine proteases. Its primary target is elastase, but it also has a moderate affinity for plasmin and thrombin. Irreversibly inhibits trypsin, chymotrypsin and plasminogen activator. The aberrant form inhibits insulin-induced NO synthesis in platelets, decreases coagulation time and has proteolytic activity against insulin and plasmin.Short peptide from AAT: reversible chymotrypsin inhibitor. It also inhibits elastase, but not trypsin. Its major physiological function is the protection of the lower respiratory tract against proteolytic destruction by human leukocyte elastase (HLE).

Function: Inhibitor of serine proteases. The primary target is elastase, but also has a moderate affinity for plasmin and thrombin.
