CST, 67118P, GST-Tag (91G1) Rabbit Monoclonal Antibody (trFluor™ Europium Cryptate Conjugate)

Monoclonal Antibody for studying . Validated for Peptide ELISA (DELFIA). Highly specific and rigorously validated in-house, GST-Tag (91G1) Rabbit Monoclonal Antibody (trFluor^™ Europium Cryptate Conjugate) (CST #67118) is ready to ship. Product Usage Information trFluorTM Europium Cryptate conjugated antibodies are ideal for protein-protein interaction assays, pair-based immunoassay technologies, or high-throughput screening where greater sensitivity and quantitative detection is needed. The long fluorescent decay time of Europium Cryptate results in improved signal to background over fluorescent dye conjugates. Methods utilizing Europium Cryptate conjugated antibodies include, but are not limited to, TR-FRET, where Europium Cryptate-labeled donor antibodies are paired with red fluorophore-labeled acceptor antibodies, such as Alexa Fluor ® 647 or APC. Please contact us if you require an acceptor antibody clone conjugated to a red dye at a custom concentration, a carrier-free formulation, or a more customized packaging solution. Note: Addition of potassium fluoride (KF) in the assay dilution buffer range of 40-400 mM is recommended for enhanced fluorescent signal. Optimal dilutions and working concentrations of both the conjugated antibodies and the KF should be determined by the end user. Storage Supplied in PBS (pH 7.2), less than 0.1% sodium azide, and 2 mg/mL BSA. Store at 4°C. Do not aliquot the antibody. Protect from light. Do not freeze. Specificity / Sensitivity GST-Tag (91G1) Rabbit Monoclonal Antibody (trFluor™ Europium Cryptate Conjugate) detects transfected GST fusion proteins. Species Reactivity: All Species Expected Source / Purification Monoclonal antibody is produced by immunizing animals with a GST fusion protein. Background Epitope tags are useful for the labeling and detection of proteins using immunoblotting, immunoprecipitation, and immunostaining techniques. Because of their small size, they are unlikely to affect the tagged protein's biochemical properties. Glutathione S-transferase (GST) is a widely used fusion partner, since it provides both an easily detectable Tag and a simple purification process with little effect on the biological function of the protein of interest. Numerous vectors containing GST-Tag have been developed for both prokaryotic and eukaryotic systems over the past decade (1-3).
