ABfinity™ antibody characteristics include:
- Validation in Western blot and Indirect ELISA
- Superior lot-to-lot consistency
- Extremely high specificity and sensitivity
- Recombinant rabbit monoclonal antibody
AS160 (AKT substrate of 160kDa), commonly known as TBC1D4 [(TBC1(tre-2/USP6,BUB2,cdc16) domain family member 4] is a 160kDa protein expressed in many tissues including brain, kidney, and liver. AS160 is a Rab GTPase activating protein (GAP) which regulates GLUT4 translocation by insulin-stimulated phosphorylation (Ref 1-3). AS160 also possesses a calmodulin-binding domain (CBD) which increases the possibility of contraction-stimulated increases in Ca(2+)/calmodulin (Ref 4). In human, the gene encoding AS160 is located on the q arm of chromosome 13 (Ref 5).
Exceptional Consistency Saves You Time and Money
ABfinity™ antibodies are produced by transfection of mammalian cells with heavy and light chain antibody cDNAs. This provides you with the highest consistency between lots, eliminating the need to revalidate your assays for each lot.
High Specificity Means More Reliable Data
The proprietary recombinant technology employed in the production of ABfinity™ antibodies means you are assured of the greatest degree of reliability. Staining of nonspecific proteins is virtually eliminated while very high sensitivity is achieved. Invitrogen has validated this antibody in Western blotting.
High Sensitivity Lets You Detect Low Levels of Target Protein
ABfinity™ antibodies demonstrate much higher sensitivity than ordinary antibodies. Proteins expressed in low levels can be detected with high specificity allowing you to use less of your precious samples than with ordinary antibodies.
Recombinant Rabbit IgG—Use Like Any Other IgG Antibody
As with traditional IgG antibodies, gel electrophoresis of ABfinity™ antibodies produces a 150 kDa band under non-reducing conditions and 50 kDa and 25 kDa bands under reducing conditions.
