E.Coli
Catalog No.
CYT-297
Description :
Recombinant Bream GH produced in E.Coli is a single, non-glycosylated,
polypeptide chain containing having a molecular mass of 21410.01 Dalton.
Bream GH shares 97% amino acid sequence identity with gilthead sea bream,
94% with red sea bream, 93% with the tuna, 91% with barramundi and 63% with the salmon.
The rbrGH is purified by proprietary chromatographic techniques.
Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation:
The protein (1mg/ml) was lyophilized after extensive dialyses against 5mM phosphate buffer, 5mg mannitol and 1mg glycine.
Solubility:
It is recommended to reconstitute the lyophilized rbrGH in sterile 18MΩ-cm
H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Stability:
Lyophilized rbrGH although stable at room temperature for 3 weeks, should be stored desiccated
below -18 C. Upon reconstitution rbrGH 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 avoid freeze-thaw cycles.
Purity:
Greater than 95.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Anion-exchange FPLC.
(c) Analysis by reducing and non-reducing SDS-PAGE Silver Stained gel.
Dimers and aggregates:
Less than 1% as determined by silver-stained SDS-PAGE gel analysis.
Endotoxin:
Less than 0.1 ng/ug (IEU/ug) of rbrGH.
Protein content:
Protein quantitation was carried out by two independent methods:
1. UV spectroscopy at 280 nm .
2. Analysis by RP-HPLC, using a standard
solution of GH as a Reference Standard.
