Endogenous Avidin + Biotin Blocking System ab3387 is used to decrease the signal caused by endogenous avidin, biotin, or biotin-binding proteins when immunostaining specimens with detection systems that rely on avidin-biotin / steptavidin-biotin (ABC systems). Non-specific staining due to these factors commonly resembles a diffuse, weak, cytoplasmic pattern.
Tested applicationsSuitable for: IHC-Fr, IHC-P, ICC/IFmore details

Storage bufferPreservative: 0.1% Sodium Azide in both components
Components 1 kit Avidin solution 1 x 15ml Biotin Solution 1 x 15ml
RelevanceSome cells, and tissues such as kidney, liver and spleen, contain endogenous biotin. Using an avidin-biotin staining method may result in high, non-specific background staining. A significant reduction of this non-specific background can be obtained by pre-treatment of cells/tissues with avidin/biotin blocking reagents prior to the incubation of biotinylated antibody.
Our Abpromise guarantee covers the use of ab3387 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|IHC-Fr||Use at an assay dependent dilution.|
|IHC-P||Use at an assay dependent dilution.|
|ICC/IF||Use at an assay dependent dilution.|
