Secondary Antibodies
Mouse Anti-rabbit IgG (Light-Chain Specific) (L57A3) mAb #3677
Protocols
- 3677:
- Western Blotting
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.
Western Blotting
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.
IP
Immunoprecipitation of PRAS40 from untreated HeLa cells using PRAS40 (D23C7) Rabbit mAb #2691 (Lane 2). All lanes are probed with PRAS40 (D23C7) Rabbit mAb #2691 as the primary antibody, including input control in lane 1. Secondary antibodies include Mouse Anti-rabbit IgG (Conformation Specific) (L27A9) mAb #3678 (Panel A), Mouse Anti-rabbit IgG (Light-Chain Specific) (L57A3) mAb (Panel B), and 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.
Description
Affinity purified mouse anti-rabbit IgG (Light-Chain Specific) antibody.
Applications
This product has been optimized for use as a secondary antibody in Western blotting applications.
Background
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.
