Placental Lactogen Human Recombinant, Placental Lactogen Human, 50ug

---

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

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

Description
Placental Lactogen Human Recombinant, is a single polypeptide chain containing 199 amino acids and an additional Ala at the N-terminus having a molecular mass of approximately 22.4 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 0.73 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 99.0% as determined by:
(a) Analysis by Gel Filtration.
(b) Analysis by SDS-PAGE.

Solubility
It is recommended to reconstitute the lyophilized Placental Lactogen in sterile water or 0.4% NaHCO3 adjusted to pH 8-9, not less than 100ug/ml, which can then be further diluted to other aqueous solutions, preferably in presence of carrier protein.

Source
Escherichia Coli.

Stability
Lyophilized Placental Lactogen Human 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.
