The green fluorescent protein (GFP) from the jellyfish Aequorea victoria is a versatile marker for monitoring physiological processes, visualizing protein localization, and detecting transgenic expression. We offer anti-GFP antibody conjugates as a rabbit IgG fraction and chicken IgY fraction conjugated to biotin, horseradish peroxidase (HRP), or fluorophore labeled. All anti-GFP antibody conjugates are suited for detection of native GFP, GFP variants, and most GFP fusion proteins by western blot analysis and immunocytochemistry. The anti-GFP rabbit polyclonal antibody is raised against GFP isolated directly from Aequorea victoria and the IgG fraction is purified by ion-exchange chromatography.

Anti-GFP conjugated to Alexa Fluor® 488 with target BacMam-GFP

Alexa Fluor® 488 dye was conjugated to two independent lots of GFP Rabbit IgG Polyclonal antibody resulting in anti-GFP Alexa Fluor® 488 (catalog number A21311). U2OS cells were transduced with CellLight® Mitochondria-GFP, BacMam 2.0 (catalog number C10508).  After an overnight incubation the cells with treated with fixation and then permeablized. GFP molecules were detected by the addition of anti-GFP Alexa Fluor® 488 (catalog number A21311). Texas Red®-X phalloidin (catalog number T7471)  was added to detect actin. Hoeschst 33342 (catalog number H3570) was used as a nuclear counterstain.

Recovering GFP signal after Click-iT ® EdU treatment

Human osteosarcoma cells transduced with CellLight® Mitochondria-GFP (catalog number C10508) samples were pulsed with EdU, fixed, and labeled with Click-iT® EdU Alexa Fluor® 555  (catalog number C10338) for cell proliferation (pink). DAPI for nuclei (blue) (catalog number D3571). GFP signal was recovered with anti-GFP Alexa Fluor® 488 (catalog number A21311) primary antibody (green).
