GFP Antibody

Detection of GFP by Western Blot. Western blot shows lysates of NS0 mouse myeloma cell line either mock transfected or transfected with eGFP-tagged EDG6. PVDF membrane was probed with 1 µg/mL of Goat Anti-GFP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4240) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for GFP at approximately 80 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

GFP in HEK293 human embryonic kidney cells transfected with GFP. GFP was detected in immersion fixed HEK293 human embryonic kidney cells transfected with GFP (green) using Goat Anti-GFP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4240) at 1.7 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red, middle panel; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to the cytoplasm of GFP-positive cells. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Detection of GFP in HEK293 human embryonic kidney cells transfected with GFP. HEK293 human embryonic kidney cells transfected with GFP was stained with Allophycocyanin-conjugated Anti-Goat IgG Secondary Antibody only (A, Catalog # F0108) or with Goat Anti-GFP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4240) followed by Secondary Antibody (B). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin. Quadrant markers were set based on control antibody staining (Catalog # AB-108-C).

Detection of GFP by Simple Western^TM. Simple Western lane view shows lysates of HEK293T human embryonic kidney cell line either mock transfected (-) or transfected with eGFP-tagged EDG6 (+), loaded at 0.2 mg/mL. A specific band was detected for GFP at approximately 114 kDa (as indicated) using 2.5 µg/mL of Goat Anti-GFP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4240) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Simple Western: GFP Antibody [Unconjugated] [AF4240] - Simple Western: GFP Antibody [Unconjugated] [AF4240] - Design for a membrane-localized ACE2 expression system. (A) Our ACE2 construct is driven by a CMV promoter followed by the first 25 residues of ACE2 containing the leader sequence that direct ACE2 to the plasma membrane. This is followed by a 3xHA tag linked to the remainder of ACE2 (20-805) and a C-terminal sfGFP. Both 3xHA and sfGFP fusions are separated from ACE2 by flexible 3xGGGGS linkers. (B) The ACE2 fusion protein is designed to be embedded in the plasma membrane where it can perform extracellular carboxypeptidase-mediated metabolism and its levels can be detected by cell staining with antibodies to HA. (C) Lysates from untransfected or 3xHA-ACE2-sfGFP-transfected HEK293 cells were analyzed by automated Jess capillary immunoassay using antibodies to HA, GFP, and two ACE2 antibodies. (D) Confocal fluorescence microscopy of HEK cells transfected with 3xHA-ACE2-sfGFP and stained with HA and the nuclear stain DAPI.
