Description：Recombinant Human CA4 Protein is produced by E.coli expression system and the target gene encoding Ala19-Lys283 is expressed with a 6His tag at the C-terminus.Form：Liquid in a 0.2 μM filtered solution of 20mM Tris-HCl, 100mM NaCl, pH 8.5.Gene Symbol：CA4Alternative Names：Carbonic anhydrase 4; Carbonate dehydratase IV; Carbonic anhydrase IV; CA-IV Entrez Gene (Human)： 762; SwissProt (Human)： P22748; Purity：Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure：MAESHWCYEV QAESSNYPCL VPVKWGGNCQ KDRQSPINIV TTKAKVDKKL GRFFFSGYDK KQTWTVQNNG HSVMMLLENK ASISGGGLPA PYQAKQLHLH WSDLPYKGSE HSLDGEHFAM EMHIVHEKEK GTSRNVKEAQ DPEDEIAVLA FLVEAGTQVN EGFQPLVEAL SNIPKPEMST TMAESSLLDL LPKEEKLRHY FRYLGSLTTP TCDEKVVWTV FREPIQLHRE QILAFSQKLY YDKEQTVSMK DNVRPLQQLG QRTVIKLEHH HHHHDirections for Use：Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.Quality Control：Endotoxin: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.Storage/Stability：Store it at -20°C to -80°C for one year. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
