Flow Cytometry Product Notes: Test Sizes: To accommodate multicolor flow cytometry, eBioscience is in the process of reducing test size volumes from 20 µL to 5 µL. Please check your antibody vial for the recommended test size. Fluorochrome Replacements: eBioscience is in the process of replacing all Alexa Fluor® 647 conjugated products with eFluor® 660 conjugated products.
Description
The polyclonal antibody reacts with green-fluorescent protein (GFP). Antibodies were affinity purified using the native GFP immobilized on a solid phase. Green fluorescent protein was originally cloned from the cnidarian, Aequorea victoria. This exceptional protein absorbs blue light (maximally at 395 nm) and emits green light (peak at 509) without the requirement of exogenous substrates and cofactors (1). These unique qualities allow GFP to be used to monitor gene expression and protein localization in vivo. Several mutant forms of GFP have been developed which fluoresce more intensely and have shifted excitation maxima when compared to the wild type GFP, making them useful for FACS, fluorescence microscopy, and double-labeling applications (2,3).
Applications Reported
Purified Anti-GFP poly has been reported for use in immunoprecipitation and immunoblotting (WB).
Applications Tested
Purified Anti-GFP poly has been tested by immunoblotting (WB). (1:1000-1:5000 starting dilution). It is recommended that this antibody be titrated for optimal performance in the assay of interest.
