TrueBlot® For Immunoprecipitation, Western Blot and IP Western Blot

TrueBlot® is a secondary antibody which enables unhindered detection of molecules. Simply substitute your conventional HRP or fluorescent reagent with mouse, rabbit, goat or sheep TrueBlot for unparalleled clarity in results and high quality imaging suitable for reproduction.


Immunoprecipitation protocols and Western Blots provide highly specific results, yet often suffer from heavy/light chain blotting, contamination, and ongoing interference. TrueBlot® products solve nearly all of these problems through increased sensitivity, less background noise, and enhanced accuracy.


 TrueBlot® reagents enable you to generate clear, best-quality data in individual Immunoprecipitation and Western Blots (Nfkb Western Blots as well as GFP Immunoprecipitation Western Blots), but can also be used when the two protocols are combined. Available in several options, from IP Agarose Beads alone, to complete IP/Western Blot kits from goat, mouse, rabbit or sheep.

View all Fluorescent Trueblot products


Rockland is proud to present a new family of products to our customers. Fluorescent TrueBlot®, a new format of our popular TrueBlot® product line, combines the power and specificity of the original products with the versatility of fluorescent and near infra-red dyes. Conjugating highly optimized TrueBlot® reagents to a full spectrum of fluorescent labels, results in multipurpose reporter molecules that can be used in a variety of immunoassays.




TrueBlot®: Clear Detection of Blotted Target Bands


Rockland’s TrueBlot® product line enables researchers to generate publication-quality western blot data for Nfkb IP Western Blots, Phospho IP Western Blots, and GFP IP Western Blots. Simply substitute your conventional HRP blotting reagent with Goat TrueBlot®, Mouse TrueBlot®, Rabbit TrueBlot® or Sheep TrueBlot®. TrueBlot® is a horseradish peroxidase conjugated immunoblotting detection reagent, which enables unhindered detection of blotted target bands. This results in unparalleled clarity in results and high quality imaging suitable for reproduction.


TrueBlot® preferentially detects the native disulfide form of mouse IgG or rabbit IgG, making it ideal for IP and Western Blot protocols involving immunoblotting of immunoprecipitated proteins. TrueBlot® reduces interference by the ~55 kDa heavy and ~23 kDa light chains of the immunoprecipitating antibody in IP/immunoblotting applications, making Phospho Immunoprecipitation Western Blot data even more accurate. TrueBlot® is also ideal for studying post-translational protein modifications, including phosphorylation, or protein-protein interactions.
