Human-on-Human HRP Polymer:

A guide to improve the use of humanized therapeutic antibody screenings

Humanized antibodies are an improving and rapidly growing class of therapeutics for treatment of human disease. Their efficacy depends highly
on specificity and sensitivity for the desired target antigen. Thus, preclinical studies of potential human (and humanized) antibody therapeutics
include immunohistochemical (IHC) screening.

A major technical problem in human antibody detection lies in non-specific staining due to endogenous human IgG. To counter this problem,
Biocare created a Human-on-Human HRP-Polymer kit designed specifically for researchers utilizing humanized antibodies on human tissues for
the development of human therapeutics. This system allows for reduced and simplified protocols while rendering high sensitivity and specificity
against the target antigen of interest.

Human-on-Human HRP Polymer Technology Benefits

 


• Elimination of FITC antibody conjugation
• Reduced antibody incubation times
• No overnight incubation steps
• Significantly reduce or eliminate background

• Highly effective ancillary reagents
• Minimum cross-reactivity to endogenous IgG
• Archivable chromogenic visualization
• Suitable for both manual & automated techniques

The detection kit provides reagents to tag the humanized primary antibody with a Digoxigenin (DIG) anti-Human Linker. Once labeled, the bound
primary antibody is detected by a Mouse anti-Digoxigenin secondary, followed by an anti-mouse HRP polymer. An HRP chromogen color of choice is
then applied to generate a permanently stained slide. This easy, modern method reduces non-specific staining with the added benefit of rapid screening.
