Cat#:RP-5295H;Product Name:Recombinant Human PTGDS Protein;Synonym:Prostaglandin-H2 D-isomerase, EC 5.3.99.2, Lipocalin-type prostaglandin-D synthase, Glutathione-independent PGD synthetase, Prostaglandin-D2 synthase, PGD2 synthase, PGDS2, PGDS, Beta-trace protein, Cerebrin-28, PTGDS, PDS, BTP, Beta Trace.;Description:The Human PTGDS His-Tagged Recombinant Protein, produced in E. coli, is 20.3 kDa protein containing 168 amino acid residues of the human PTGDS and 14 additional amino acid residues - HisTag (underlined).;Source:E.coli;AA Sequence:MRGSHHHHHH GMASAPEAQV SVQPNFQQDK FLGRWFSAGL ASNSSWLREK KAALSMCKSV VAPATDGGLN LTSTFLRKNQ CETRTMLLQP AGSLGSYSYR SPHWGSTYSV SVVETDYDQY ALLYSQGSKG PGEDFRMATL YSRTQTPRAE LKEKFTAFCK AQGFTEDTIV FLPQTDKCMT EQ.;Purity:Greater than 95.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.;Formulation:Filtered (0.4 micron) and lyophilized from 0.5 mg/ml in 20mM Tris buffer, 20mM NaCl, pH 7.5.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized PTGDS in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized PTGDS although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution PTGDS 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.;
