Background Information
Green Fluorescent Proteins (GFPs) encompass a diverse range of proteins carrying a green chromophore, originating from various species and forming different protein lineages.
Wildtype GFP consists of 238 amino acid residues (26.9 kDa). GFP was first identified in the jellyfish Aequorea victoria. It emits green light with a peak wavelength of 509 nm upon excitation by blue light at 395 nm.
When fused with other proteins, GFP serves as a versatile reporter protein e.g. for quantifying expression levels or facilitates visualization of subcellular localization through fluorescence microscopy.
This antibody is a rabbit polyclonal antibody, generated against the full-length eGFP protein. It exhibits reactivity towards variants of Aequorea victoria GFP, including S65T-GFP, RS-GFP, YFP, CFP, and eGFP.

FH Paul (Verified Customer) (01-15-2020) | Works well for WB.
|
FH Laura (Verified Customer) (01-14-2020) | Good sensitivity for Western blot.
|
FH Aamir (Verified Customer) (01-08-2020) | Works well for WB and IF
|
FH Erica (Verified Customer) (09-26-2019) | This antibody works very well with both western blots and IP. We previously used GFP antibody from another company and it didn't work well. We then switched to Proteinntech's and the signal was very strong! Highly recommend!
|
FH Mayur (Verified Customer) (04-30-2019) | The H4 cells were transfected with pcDNA only and pcDNA EGFP . The expression of the EGFP was measured using the GFP antibody from ProteinTech. Great antibody.
