 Product Name   

placental growth hormone 20K, Recombinant Protein

★Popular Item★
 Also Known As   

Human placental growth hormone 20K

 Product Synonym Names    Human placental growth hormone 20K
 Research Use Only    For Research Use Only. Not for use in diagnostic procedures.
Table BarTOPTable Bar
 Sequence    The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Phe-Pr o-Thr-Ile.
Section Bar
 Host    Escherichia Coli
Section Bar
 Purity/Purification    Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Gel filtration at non denaturing conditions using 25 nM Tris-HCl + 150 nM NaCl, pH 11.
(c) Analysis by reducing and non-reducing SDS-PAGE Silver Stained gel.
 Form/Format    The protein was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3 previously adjusted pH 11.
Section Bar
 Solubility    It is recommended to reconstitute the lyophilized rHuGH-20K-pl in 0.4% NaHCO3 or water adjusted to pH 11, not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
 Protein Content    Protein quantitation was carried out by two independent methods:
1. UV spectroscopy at 280 nm using the absorbency value of 1.14 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).
2. Analysis by RP-HPLC, using a calibrated solution of GH-20K-pl as a Reference Standard.
 Dimers and Aggregates    Less than 3% as determined by silver-stained SDS-PAGE gel analysis.
 Endotoxin    Less than 0.1 ng/ug (IEU/ug) of human GH.
 Formulation    The protein was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3 previously adjusted pH 11.
 Biological Activity    PLR'r HuGH-20K is fully biologically active when compared to World Health Organization (WHO) reference standard as evidenced by in vitro bioassay. It is also capable of forming a 1:2 complex with the recombinant human growth hormone receptor extracellular domain (ECD).
Section Bar
 Preparation and Storage    Lyophilized rHuGH-20K-pl although stable at room temperature for 3 weeks, should be stored desiccated below -18 degree C. Upon reconstitution and filter sterilization rHuGH-20K-pl can be stored at 4 degree C, pH 11 for up to 4 weeks. For long term storage and more diluted solutions it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
 Other Notes    Small volumes of placental growth hormone 20K recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
