哪里有销售巴曲酶 重组巴曲酶/Batroxobin

Synonyms	Thrombin-like enzyme batroxobin, EC 3.4.21.74, BX, Bothrops atrox serine proteinase, Venombin-A, Defibrase, Reptilase, Batroxobin.
Introduction	Batroxobin is a serin protease that reduces fibronogen levels and is originally extracted from snake venom of Bothrops Atrox. Batroxobin is used in defibrinogenation and thrombolysis and also has an effect on c-fos gene and growth factor. Batroxobin can efficiently restrain proliferation of VSMCs, by blocking the release and uptake of Ca2+, thus influencing [Ca2+]i. Batroxobin is a single chain glycopeptide with a molecular mass of 43kDa on SDS-PAGE gel and its pI-6.6. Batroxobin converts fibrinogen to fibrin through the restricted release of fibrinopeptide-A from fibrinogen to promote blood to clot. Unlike thrombin, it is not affected by heparin and hirudin.
Description	The Batroxobin Recombinant Protein, produced in yeast, is a single, glycosilated polypeptide chain containing 231 amino acids and having an Mw of approximately 28-33 kDa.
Source	Pichia Pastoris.
Physical Appearance	Sterile Filtered white lyophilized powder.
Formulation	The Batroxobin protein was lyophilized from a concentrated (1mg/ml) solution containing 20mM sodium acetate buffer, pH 7.4.
Solubility	It is recommended to reconstitute the lyophilized Batroxobin in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability	Batroxobin although stable at room temperature for 3 weeks, should be stored below -18°C. Upon reconstitution EGF should be stored at 4°C between 2-7 days and for future use below  -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
Purity	Greater than 97.0% as determined by (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Biological Activity	Batroxobin’s biological activity was found to be of no less than 500KU/mg. (Klobusitzky Unit).
