CAT No.BT-CYT-512

Placental Lactogen Ovine Recombinant, Placental Lactogen Ovine, 50ug

---

Amino acid sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Gln-His-Pro-Pro.

Biological Activity
Placental Lactogen Ovine is biologically active as evidenced by inducing proliferation of Nb2 cells.

Description
Placental Lactogen Ovine 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.

The protein was lyophilized from a concentrated (1mg/ml) solution with 0.02-0.03% NaHCO3.

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).

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 18M¦¸-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Source
Escherichia Coli.

Stability
Lyophilized Placental Lactogen Ovine Recombinant although stable at room temperature for 3 weeks, should be stored desiccated below -18¡ãC. Upon reconstitution Placental Lactogen should be stored at 4¡ãC between 2-7 days and for future use below -18¡ãC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.

Synonyms
Chorionic Somatomammotropin Hormone 1, CSH1, CS-1, hCS, PL.
