Western blot analysis of decreasing concentrations of total rabbit IgG reduced and denatured in 1X SDS loading buffer with DTT using Mouse Anti-rabbit IgG (Conformation Specific) (L27A9) mAb #3678 (Panel A), Mouse Anti-rabbit IgG (Light-Chain Specific) (L57A3) mAb (Panel B), or Anti-rabbit IgG, HRP-linked Antibody #7074 (Panel C). For Panels A and B, the bound mouse anti-rabbit IgG mAb was detected by Anti-mouse IgG, HRP-linked Antibody #7076. The positions of the reduced and denatured rabbit IgG heavy and light chains are indicated.

Product Usage Information

Storage: Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA, 50% glycerol and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

Product Description

Affinity purified mouse anti-rabbit IgG (Light-Chain Specific) antibody. This product has been optimized for use as a secondary antibody in Western blotting applications.


Specificity / Sensitivity

Mouse Anti-rabbit IgG (Light-Chain Specific) (L57A3) mAb recognizes the light chain of rabbit IgG, either in native conformation or denatured and reduced form. It does not bind to the denatured and reduced rabbit IgG heavy chain (about 50 kDa) on western blot.


Source / Purification

Monoclonal antibody is produced by immunizing animals with native total rabbit IgG.

Mouse Anti-rabbit IgG (Light-Chain Specific) (L57A3) mAb only reacts with the light chain of rabbit IgG and does not bind to the denatured and reduced rabbit IgG heavy chain. When performing immunopreciptiation (IP) followed by western blotting, the denatured rabbit IgG heavy chain of the primary antibody used for IP runs at approximately 50 kDa on the subsequent western blot and can often obscure bands of proteins that have a similar molecular weight. Using Mouse Anti-Rabbit IgG (Light-Chain Specific) (L57A3) mAb as a secondary antibody will eliminate this problem.
