Cat#:RP-4474H;Product Name:Recombinant Human MDH1 Protein;Synonym:MDH-s, MDHA, MOR2.;Description:MDH1 Protein produced in E.coli is a single, non-glycosylated polypeptide chain containing 342 amino acids (1-334 a.a.) and having a molecular mass of 37.4 kDa. The MDH1 is fused to an 8 amino acid His tag at C-terminus and purified by conventional chromatography.;Source:E.coli;AA Sequence:MSEPIRVLVT GAAGQIAYSL LYSIGNGSVF GKDQPIILVL LDITPMMGVL DGVLMELQDC ALPLLKDVIA TDKEDVAFKD LDVAILVGSM PRREGMERKD LLKANVKIFK SQGAALDKYA KKSVKVIVVG NPANTNCLTA SKSAPSIPKE NFSCLTRLDH NRAKAQIALK LGVTANDVKN VIIWGNHSST QYPDVNHAKV KLQGKEVGVY EALKDDSWLK GEFVTTVQQR GA;Purity:Greater than 95.0% as determined by SDS-PAGE.;Bioactivity:Specific activity is > 8 units/mg, and is defined as the amount of enzyme that cleaves 1umole of oxalacetate and beta-NADH to L-malate and beta-NAD per minute at pH7.5 at 25°C.;Formulation:The MDH1 1mg/ml protein solution contains 20mM Tris-HCl pH-8, and 10% glycerol.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Storage:MDH1 although stable 4°C for 4 weeks, should be stored desiccated 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.;
