Cat#:RP-5096H;Product Name:Recombinant Human Placental Lactogen Caprine;Synonym:Chorionic Somatomammotropin Hormone 1, CSH1, CS-1, hCS, PL.;Description:Placental Lactogen Caprine Recombinant, is a single polypeptide chain containing 199 amino acids and an additional Ala at the N-terminus having a molecular mass of 23 kDa. Placental Lactogen Recombinant Goat is purified by proprietary chromatographic techniques.;Source:E.coli;AA Sequence:The sequence of the first four N-terminal amino acids was determined and was found to be Ala-Glu-Asn-Tyr.;Purity:Greater than 98.0% as determined by: (a) Analysis by SEC-HPLC. (b) Analysis by SDS-PAGE.;Bioactivity:Placental Lactogen Caprine is biologically active as evidenced by inducing proliferation of Nb2 cells.;Formulation:The protein was lyophilized from a concentrated (1mg/ml) solution with 0.02-0.03% NaHCO3.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized Placental Lactogen in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized Placental Lactogen Caprine Recombinant although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Placental Lactogen Goat 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.;
