Along with Fc receptors, frequent causes of background staining are endogenous enzyme activity, if you use peroxidase or alkaline phosphatase as enzyme markers on your secondary antibodies, and endogenous biotin when using a streptavidin or avidin reagents ( http://www.ihcworld.com/ ; http://www...
antibodies and for the preparation of negative control reagents in IHC. This product is particularly useful for reducing background staining while maintaining specific reactivity. Antibody Diluent with Background Reducing Components can also be used to stabilize diluted antibodies when stored at 2–8°C...
Intended use For In Vitro diagnostic use.This product is intended for use as a diluent in the preparation of primary antibodies and negative controlreagents. It is to be used with antibodies and/or antigens that yield high background in immunohistochemical(IHC) staining procedures.Refer to the ...
To reduce background staining in IHC, ICC and other immunostaining methods, samples are incubated with a buffer that blocks the reactive sites to which the primary or secondary antibodies may otherwise bind. Da bi se smanjila boja pozadine IHC, primjenjuju se ICC i drugi imunobojeći metodi...
19 In digitised images of IHC staining, four random 0.25-mm2 squares were drawn and positive cells in the tumour region were counted, giving mean values per 0.25 mm2. Lymph follicles and germinal centres were identified on the basis of their morphological appearance and positive staining for...
For the assessment of the ALK status, ALK expression was classified as positive if strong granular cytoplasmic staining in tumor cells was present [32]. Positive cases were confirmed using fluorescence in situ hybridization (FISH) following a standardized protocol described below (Fluorescence in situ...

CONTEXT: Immunohistochemical (IHC) stains have known utility in prostate biopsies and are widely used to augment routine staining in difficult cases. Patterns in IHC utilization and differences based on pathologist training and experience is understudied in the peer-reviewed literature. OBJECTIVES: To ...
General overall background staining may occur if insufficient washing is performed after polymer application. Due to the large size of polymer conjugates, the diffusion rate of these molecules is lower than for low-molecular weight conjugates. In addition, polymer conjugates based on a hydrophobic ...
