Overview

Synonyms	Rabbit Anti-TAP-tag pAb; Anti-TAP-tag pAb
Description	Well-characterized antibodies against short-sequence epitope tags are common in the study of protein expression in several different expression systems. The TAP (tandem affinity purification)-tag allows rapid purification of complexes from a relatively small number of cells even if the researcher does not have prior knowledge of the complexs composition, activity, or function. Combined with mass spectrometry, the TAP-tag strategy enables the identification of proteins interacting with a given target protein¹. GenScript Rabbit Anti-TAP-tag Polyclonal Antibody is generated against the common tag, which is composed of a 21-residue peptide, CSSGALDYDIPTTASENLYFQ, derived from the C-terminus of the TAP-tag construct after TEV cleavage.
Host Species	Rabbit
Conjugation	Unconjugated
Immunogen	Peptide CSSGALDYDIPTTASENLYFQ conjugated to KLH
Purification	Immunoaffinity chromatography

Properties

Subclass	Rabbit IgG
Concentration	0.5 mg/ml, lyophilized with PBS, pH 7.4, containing 0.02% sodium azide.
Reconstitution	Reconstitute the lyophilized powder with deionized water (or equivalent) to an antibody concentration of 0.5 mg/ml.
Specificity	Rabbit Anti-TAP-tag Polyclonal Antibody specifically reacts with fusion proteins containing TAP epitope tag.
Storage	The antibody is stable in lyophilized form if stored at -20°C or below. The reconstituted antibody can be stored for 2-3 weeks at 2-8°C. For long term storage, aliquot and store at -20°C or below. Avoid repeated freezing and thawing cycles.

Working concentrations for specific applications should be determined by the investigator. The appropriate concentrations may be affected by secondary antibody affinity, antigen concentration, the sensitivity of the method of detection, temperature, the length of the incubations, and other factors. The suitability of this antibody for applications other than those listed below has not been determined. The following concentration ranges are recommended starting points for this product.
ELISA: 0.05-0.2 µg/ml
Western blot: 0.1-1.0 µg/ml
Western blot using ONE-HOUR Western^TM Kit: For quick results, GenScript ONE-HOUR Western^TM Kit L00204C is recommended. 10 µg of this antibody is mixed with 10 ml of WB solution for 8 cm x 8 cm membrane.
immunoprecipitation (IP):2-10 µg/mg of lysate
Other applications: user-optimized
