EGFP/GFP/Venus antibody

Antigen: EGFP/GFP/Venus

Clonality: Polyclonal

Host: Rabbit

Application: Immunohistochemistry (IHC), Western Blotting (WB)

Catalog no.: ABIN350304

Additional Information

Immunogen: Synthetic peptides (a pentamer) from EGFP/GFP conjugated to an immunogenic carrier protein was used as the immunogen.

Format: Lyophilized

Isotype: IgG

Description: GFP is a  naturally fluorescent protein, discovered by chance in the 1960s by Shimomura et al. GFP makes green light out of aequorin’s blue light. The chromophore is a modified Ser-Tyr-Gly sequence. GFP can emit light once this short tripeptide has adopted a cyclic conformation with the help of a oxygen. BIOPHYSICOCHEMICAL PROPERTIES: Excitation max (nm): 488; Emission max (nm): 509; Extinction coefficient (Cm-1M-1): 61000. Fluorescent proteins have become a useful and ubiquitous tool for making chimeric proteins, where they function as a fluorescent protein tag. Typically they tolerate N- and C-terminal fusion to a broad variety of proteins. They have been expressed in most known cell types and are used as a noninvasive fluorescent marker in living cells and organisms. They enable a wide range of applications where they have functioned as a cell lineage tracer, reporter of gene expression, or as a measure of protein-protein interactions. Also known as: (Enhanced) Green Fluorescence Protein.

Specificity: Appears to be specific for EGFP/GFP.

Application Details

Application Notes: IHC, WB. A working concentration of 5-50 µg/ml is recommended. The optimal concentration should be determined by the end user.

Purity: IgG

Storage: Maintain the lyophilised/reconstituted antibodies frozen at -20°C for long term storage and refrigerated at 2-8°C for a shorter term. When reconstituting, glycerol (1:1) may be added for an additional stability. Avoid freeze and thaw cycles.

Restrictions: For Research Use only
