Western blot shows synthetic eGFP, recombinant RANGAP-1 tagged with eYFP, recombinant GRPuv, and crystal jelly GFP. PVDF membrane was probed with 2 µg/mL of Mouse Anti-GFP Monoclonal Antibody (Catalog # MAB42402) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF018). A specific band was detected for GFP at approximately 28 and recombinant RANGAP-1 tagged with eYFP at 45 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

GFP in HEK293 Human Cell Line Transfected with GFP.

GFP was detected in immersion fixed HEK293 human embryonic kidney cell line transfected with GFP (green; right panel) using Mouse Anti-GFP Monoclonal Antibody (Catalog # MAB42402) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red, left panel; NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm. Staining was performed using our protocol for Fluorescent ICC Staining of Non-adherent Cells.

Detection of GFP in HEK293 Human Cell Line Transfected with eGFP by Flow Cytometry.

HEK293 human embryonic kidney cell line transfected with protein tagged with either eGFP (filled histogram) or mCherry (open histogram) was stained with Mouse Anti-GFP Monoclonal Antibody (Catalog # MAB42402) or Mouse IgG2B Isotype Control (MAB0041, data not shown) followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (F0101B). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (FC005). Staining was performed using our Staining Intracellular Molecules protocol.

Background: GFP

Green fluorescent protein (GFP) is a 27 kDa protein originally isolated from the jellyfish victoria. In the presence of UV light (490-520 nm), it emits a green fluorescent color that can be used to pinpoint locations of various intracellular proteins. GFP is 238 amino acids (aa) in length. It is a globular monomer that has a tendency to dimerize. The monomer has the shape of a beta -barrel with a chromophore (aa 65-67) containing alpha -helix running up its center. +36 GFP is a superpositively charged GFP variant that can penetrate mammalian cells with potencies much greater than that of cationic peptides or modestly cationic engineered proteins. Low molar concentrations of the protein can be observed within minutes of exposure.
