About this item

>97% Pure Recombinant Enhanced Green Fluorescent Protein (EGFP).

The recombinant EGFP is expressed and purified from transformed E. coli using a method that ensures high purity and maximal GFP fluorescence. Endotoxin has been removed, so the protein is suitable for in vivo injection or cell culture applications. The recombinant EGFP (UniProt Accession No. P42212) is a 32.7 kDa monomer with 293 amino acids tagged with 6XHis on both N- and C-terminus. Therefore, the EGFP can be detected by both His-tag antibody (Cat. No. 3998-100) and GFP antibody (Cat. No. 3999-100) on Western Blot analysis. The excitation and emmission spectra for the recombinant EGFP is identical to GFP purified from Aequorea victoria (Chalfie et al, 1994), with Ex/Em = 488/507 nm (e489 nm = 55000 M⁻¹ Cm⁻¹; e280 nm = 21980 M⁻¹ Cm⁻¹).
