Serum from donors has been tested and found negative for hepatitis BSAg, HCV, HIV1, and HIV2 by currently approved FDA methods. However because no test method can offer complete assurance that HIV, HCV or other infectious agents is absent, this material should be handled at BioSafety Level 2 as recommended for any potentially infectious human serum or blood specimen in the CDC/NIH manula "Biosafety in Microbiological and Biomedical Laboratories," 1984.


Description: Recombinant Human Growth Hormone (rHuGH)   HIGH PURITY


Price: $440.00/1mg      $312.00/mg 10 or more   Larger sizes quoted on request


Concentration: 1 mg lyophilized

Specific Activity: 3 U/mg when compared to WHO reference standard

Packaging: sterile filtered prior to lyophilization. The protein was lyophilized from 5mg/ml stock after extensive dialysis against 1.7mg sodium phosphate buffer (0,1mg sodium phosphate monobasic and 1.6mg sodium phosphate dibasic) Endotoxin <0.1ng/ug (1EU/ug) of rhuGH

Derivation: produced in E Coli as a single, non glycosylated. polypeptide chain containing 192 amino acids and having a predicted molecular mass of 22,260 daltons Purified by a proprietary chromatographic technique. amino acid composition in total agreement with the expected amino acid composition of native human growth hormone

Solubility: very soluble in water and most aqueous buffers. Recommend diluting in sterile DI water followed by addition of suitable carrier to any diluted material as 1-3% BSA/HSA.

Purity: > 99% as determined by RP-HPLC, anion- exchange FPLC and analysis by reducing and non-reducing SDS-PAGE Silver stained. <1% dimer and aggregates as determined by silver stained SDS-PAGE gel analysis.

Protein content: A280 extinction coefficient 0.72 for 0.1% 1mg/ml solution.

Storage: Lyophilized material although stable at room temp for several weeks is best stored desiccated at -20 DEG C . After reconstitution, store at 4-8 DEG C for up to 1 month or make working aliquots and store -20 DEG C. Avoid frequent freeze thaw cycles.
