Immunofluorescence / IF / ICC Antibody-GFP tag

Epitope tags and anti-epitope tag antibodies are widely used for purification and detection of recombinant proteins in immunoblotting, immunostaining and immunoprecipitation.Epitope tagging is widely used in the characterization of newly discovered proteins. With the development of biological technology, researchers can by recombinant DNA techniques, to construct containing the target gene and epitope tagged fusion protein, and then through the specific tag antibody on the identification and purification, in order to achieve the research needs.The major categories:Many different epitope tags have been engineered into recombinant proteins. Sino Biological Inc. has antibodies against FLAG®( DYKDDDDK), HA, HIS-tag, c-Myc, GFP, GST, V5, S-tag, T7-tag, E-tag and Glu-Glu tag.

Tag antibody is a special area or group that determines the specificity of the antigen molecule, and is the structure or sequence of the antibody specific binding. With the development of biological technology, researchers can construct the fusion protein containing target gene and epitope tagged by DNA recombination technology, and then identify and purify the specific tag antibody to meet the requirements of the research.

The green fluorescent protein (GFP) is a protein that exhibit bright green fluorescence when exposed to blue light. GFP always used as tag in protein. Antibody against GFP-tag is often used in biological research and related fields. Antibody against E-tag is often been used in the detection of WB and immunofluorescence. Antibody against GFP-tag is also often been used to study the expression of proteins and the interaction between proteins and proteins.

Catalog: 13105-MM05

Immunofluorescence staining of GFP protein in CHO cells, transfected with GFP. Cells (left: GFP, middle: antibody, right: merge) were fixed with 4% PFA, blocked with 10% serum, and incubated with Mouse anti-GFP monoclonal antibody (15 µg/ml) at 37℃ 1 hour. Then cells were stained with the Alexa Fluor® 594-conjugated Goat Anti-mouse IgG secondary antibody (red) and counterstained with DAPI (blue).
