| Formulation |
Lyophilized without any additives. |
| Solubility |
It is recommended to reconstitute the lyophilized Protein G in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions. |
| Purity |
Greater than 95.0% as determined by SDS-PAGE and HPLC analyses. |
| Description |
Cys-Protein G Recombinant produced in E.Coli is a 196 amino acids protein which contains amino acid 190-384 of the Streptococcus sp and a Cysteine residue at the N-terminus, has a predicted molecular mass of approximately 22.5kDa. But it migrates with an apparent molecular mass of 32kDa in SDS-PAGE.The Protein G is purified by proprietary chromatographic techniques. |
| Expression host |
Escherichia Coli. |
| Reagent Appearance |
Sterile Filtered White lyophilized (freeze-dried) powder. |
| Stability |
Lyophilized Protein G although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Protein G should be stored at 4°C between 2-7 days and for future use below -18°C.Please prevent freeze-thaw cycles. |
