Formulation |
The EGFP was lyophilized from a 0.2um filtered concentrated solution in PBS pH 7.4. |
Solubility |
It is recommended to reconstitute the lyophilized EGFP in sterile distilled H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions. |
Purity |
Greater than 95.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. |
Description |
Recombinant EGFP produced in E.coli cells is a non-glycosylated, homodimeric protein containing 239 amino acid chain and having a molecular mass of 26.9kDa. EGFP is purified by proprietary chromatographic techniques. |
Protein Background |
GFP, also known as Green Fluorescent Protein, is a protein produced by the jellyfish (Aequorea Victoria) that produces bioluminescence in the green zone of the noticeable spectrum. Green Fluorescent Protein is a useful and ubiquitous instrument for producing chimeric proteins, where it functions as a fluorescent protein tag. GFP is expressed in most known cell types and is used as a noninvasive fluorescent marker in living cells and organisms. Green Fluorescent Protein permits a broad range of applications where it has functioned as a cell lineage tracer, reporter of gene expression, or as a measure of protein-protein interactions. Enhanced GFP (eGFP) has F64L and S65T mutations, which make GFP show increased fluorescence and fold more efficiently under 370. |
Expression host |
Escherichia Coli. |
Synonyms |
Green fluorescent protein, GFP. |
Reagent Appearance |
Sterile Filtered White lyophilized (freeze-dried) powder. |
Stability |
Lyophilized EGFP although stable at room temperature for 3 weeks, should be stored desiccated below -180C. Upon reconstitution EGFP should be stored at 40C between 2-7 days and for future use below -180C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. |
