Description:
                    Recombinant rbGHBP, one polypeptide chain containing 248 amino acids and having a molecular mass of  ~ 28 kDa, Rabbit GHBP was purified by proprietary chromatographic techniques, (see Sakal et al. Prep Biochem Biotechnol. 30:107-23, 2000).

                    Physical Appearance:
                    White lyophilized (freeze-dried) powder.
                Formulation:
                    The protein was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3.
                Solubility:
                    It is recommended to reconstitute the lyophilized rbGHBP in sterile 0.4% NaHCO3 adjusted to pH 10, not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
                Stability:
                    Lyophilized rbGHBP although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution at > 0.1 rbGHBP mg/ml and filter sterilization hGHBP can be stored at 4C for several weeks. At lower concentration addition of a carrier protein (0.1% HSA or BSA) is suggested. Please prevent freeze-thaw cycles.
                Purity:
                    Greater than 98.0% as determined by:
(a) Gel filtration analysis.
(b) Analysis by reducing and non-reducing SDS-PAGE gel.
                (a) Gel filtration analysis.
(b) Analysis by reducing and non-reducing SDS-PAGE gel.
Amino Acid Sequence:
                    The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Phe-Ser-Gly-Ser.
                Dimers and Aggregates:
                    The purified rbGHBP (28K) consists of > 98% monomers as determined by gel-filtration chromatography.
                Biological Activity:
                    PLR’s hGHBP is fully biologically active as evidenced by its ability of forming 2:1 complex with non-primate GHs.
                Endotoxin:
                    Less than 0.1 ng/µg (IEU/µg) of rbGHBP (28 K).
                Protein content:
                    Protein quantitation was carried out by UV spectroscopy at 280 nm using the absorbency value of 2.64 as the extinction coefficient for a 0.1% (1mg/ml) solution at pH 8.0.  This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics). 
                Usage:
                    This material is offered by PLR for laboratory research
