Angiopoietin-2 (Angpt2), recombinant rat

Organism: Rattus norvegicus (Rat). Source: Yeast. Expression Region: 19-496aa. Protein Length: Full Length of Mature Protein. Tag Info: C-terminal 6xHis-tagged. Target Protein Sequence: YNNFRKSVDS TGRRQYQVQN GPCSYTFLLP ETDSCRSSSS PYMSNAVQRD APLDYDDSVQ RLQVLENILE NNTQWLMKLE NYIQDNMKKE MVEIQQNVVQ NQTAVMIEIG TSLLNQTAAQ TRKLTDVEAQ VLNQTTRLEL QLLQHSISTN KLEKQILDQT SEINKLQDKN SFLEKKVLDM EDKHSVQLQS MKEQKDQLQV LVSKQSSVID ELEKKLVTAT VNNSVLQKQQ HDLMETVNSL LTMMSSPDYK SSVAVPKEEK TTFRDCAEIF KSGLTTSGIY TLTFPNSTEE VKAYCDMDMG GGGWTVIQHR EDGSVDFQRT WKEYKEGFGS PLGEYWLGNE FVSQLTSGHR YVLKIQLKDW EGSEAHSLYE HFYLSGEESN YRIHLTGLTG TAGKISSISQ PGSDFSTKDS DNDKCICKCS QMLTGGWWFD ACGPSNLNGQ YYPQKQNTNK FNGIKWYYWK GSGYSLKATT MMIRPADF. Purity: Greater than 95% 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: Binds to TEK/TIE2, competing for the ANGPT1 binding site, and modulating ANGPT1 signaling. Can induce tyrosine phosphorylation of TEK/TIE2 in the absence of ANGPT1. In the absence of angiogenic inducers, such as VEGF, ANGPT2-mediated loosening of cell-matrix contacts may induce endothelial cell apoptosis with consequent vascular regression. In concert with VEGF, it may facilitate endothelial cell migration and proliferation, thus serving as a permissive angiogenic signal. Involved in the regulation of lymphangiogenesis. Reference: n/a.
