25 ug of HeLa cell lysate spiked with 3.5 ug of mouse IgG was run in lanes 2, 3, 5 and 6 under reducing conditions on SDS PAGE using the Bio-Rad V3 system and transferred to PVDF membrane. Bio-Rad Precision Plus MW marker was run in lanes 1 and 4. Mouse anti actin gamma (VMA00049) was used to detect actin gamma (approximate MW of 46 kDa) in lanes 2 and 5 only. Lanes 3 and 6 were used as controls to detect the background signaling of the secondary detection agent (no primary antibody control).. TidyBlot Western Blot Detection Reagent:HRP was used as the secondary reagent in lanes 2 and 3 and an HRP conjugated anti-mouse IgG heavy and light chain antibody was used as the secondary in lanes 5 and 6. The Blot was visualized with the Bio-Rad Chemidoc™ Touch Imaging System. The TidyBlot Western Blot Detection Reagent:HRP only bound to the native actin gamma antibody whereas the standard anti-Mouse IgG heavy and light recognized both the native and denatured antibodies

HeLa (lane 2) cell lysate was run under reducing conditions on SDS PAGE using the Bio-Rad V3 system and transferred to a PVDF membrane. Bio-Rad Precision Plus molecular weight marker was run in lane 1. Rabbit anti Human GAPDH (AHP1628) was used as the primary antibody at a dilution of 1/1000 in lane 2. TidyBlot was used at 1/200 as the secondary detection reagent. Visualization was carried out using the Bio-Rad ChemiDoc with automatic exposure

Western blot analysis of GAPDH IP samples. IP was performed on Jurkat cell lysates using 10 µg (lanes 1 & 7), 5 µg (lanes 2 & 8), 1 µg (lanes 3 & 9) Mouse anti GAPDH antibody (MCA4739), and 10 µg Mouse IgG1 Negative Control (lanes 4 & 10) (MCA1209).

8.75 µl of each IP was loaded onto an AnykD™ Criterion™ TGX Stain-Free™ gel. 8.75 µl Jurkat whole cell lysate (WCL) was run in lanes 5 & 11 while Precision Plus Protein™ Prestained Standards were run in lane 6.

Rabbit anti GAPDH antibody (VPA00187) was used at 1/1000 in lanes 1-5. HRP conjugated Tidyblot™ (STAR209P) was used at 1/200 and visualized on the Bio-Rad Chemidoc™ Touch Imaging System. Arrow points to GAPDH (molecular weight 37 kDa).

(Rated 5.0 out of 5 based on 1 customer reviews)
    TidyBlot™ Western Blot detection reagent:HRP exclusively binds to native non-denatured antibodies and does not recognize IgGs present in your immunoprecipitate or lysate. By using TidyBlot you can therefore avoid background from IgG heavy and light chains.

      • N.B. Reactivity of TidyBlot™ Western Blot Detection Reagent:HRP to mouse IgG1 can be variable. Bio-Rad recommend customers assess compatibility with their IgG1 antibodies via dot blot assay.

        TidyBlot™ Western Blot Detection Reagent:HRP specifically binds to native (non-reduced) antibodies. In contrast to conventional secondary antibodies, TidyBlot™ therefore enables the detection of immunoblotted target protein bands without interference from denatured IgG. Sources of denatured IgG include endogenous IgGs present in cell/tissue lysate and primary antibodies released from beads during immunoprecipitation experiments. The latter are particularly obstructive when detecting of (co-)immunoprecipitated proteins as IgG heavy (~50 kDa) and light chains (~25 kDa) may mask the protein(s) of interest.

        TidyBlot™ Western Blot Detection Reagent:HRP preferentially binds to the native antibody used during the Western Blot procedure rather than the SDS-denatured/reduced form present in lysates/immunoprecititates. Best results are therefore achieved by denaturing the immunoprecipitate/lysate fully (consider the duration of boiling the sample to reduce IgG disulphide bonds and the type/concentration of reducing agent).

      • Where this product has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the product for use in their own system using appropriate negative/positive controls.
      • Technical Advice
        Note: If using mouse IgG1, perform a dot blot to determine compatibilty. TidyBlot™ Western Blot Detection Reagent:HRP might not detect mouse IgG1.

                Great for IPs
                Submitted: 21 Jun 2016
                The main purpose our lab got TidyBlot for was in use for detecting p53 in IPs. As p53 runs very close to the heavy chain, it is always a struggle to detect p53 in a counterblot. TidyBlot was able to detect p53 without any heavy chain problems. I would recommend using it at a very high concentration (as noted in the protocol). I tried getting away with using less (1:1000) to conserve the product, but true to the protocol a much higher concentration was needed. Overall a great product that we will continue to use for our IPs!
