General description

Monoclonal Anti-Green Fluorescent Protein (GFP) (mouse IgG1 isotype) is derived from the hybridoma GSN149 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a synthetic peptide of the Green fluorescent protein from jellyfish Aequorea victoria. GFP is a 27 kDa protein (238 amino acids) that can produce a strong green fluorescence without the need for a substrate. It absorbs light maximally at 395 nm and emits a bright green fluorescence with a peak at 509 nm. The GFP chromophore is formed through cyclization and oxidation of an internal tripeptide motif (Ser65, Gly69 and Tyr66).
The antibody reacts specifically with GFP-fusion proteins.

Application

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Monoclonal Anti-Green Fluorescent Protein (GFP) antibody produced in mouse was used in surface plasmon resonance (SPR) gold chip analysis to study the cysteine- and domain-mediated immobilization of enhanced GFP model protein.

Biochem/physiol Actions

GFP is implicated in protein detection and localization in living cells, as well as gene expression monitoring in prokaryotes and eukaryotes. It detects protein-protein interactions in living cells.
Green fluorescent protein, produced in the jellyfish, Aequorea victoria, acts as secondary fluorescent protein in an energy transfer reaction to produce green light. It ability to produce a highly visible, internal fluorophore is widely applicable as marker for gene expression and to produce chimeric proteins to understand protein biochemistry.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
