Catalog #: CYT-511
Description:
Placental Lactogen Bovine 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 is purified by proprietary chromatographic techniques.
Synonyms:
Chorionic Somatomammotropin Hormone 1, CSH1, CSB, CS-1, hCS-B, BPL, BPLP-I.
Source:
Escherichia Coli.
Amino Acid Sequence:
The sequence of the first six N-terminal amino acids was determined and was found to be Ala-Glu-Asp-Tyr-Ala-Pro.
Purity:
Greater than 98.0% as determined by:
(a) Analysis by SEC-HPLC.
(b) Analysis by SDS-PAGE.
Solubility:
It is recommended to reconstitute the lyophilized Placental Lactogen in sterile 18MΩ–cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
Formulation:
The protein was lyophilized from a concentrated (1mg/ml) solution with 0.02-0.03% NaHCO3.
Stability:
Lyophilized Placental Lactogen Bovine Recombinant although stable at room temperature for 3 weeks, should be stored desiccated below -18 °C. Upon reconstitution Placental Lactogen 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.
Activity:
Placental Lactogen Bovine is biologically active as evidenced by inducing proliferation of Nb2 cells.
Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.
Protein Content:
UV spectroscopy at 280 nm using the absorbency value of 0.85 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
Usage:
