Blocking Reagent for Immunoassays with Phospho-Specific Antibodies: Blocking One-P

Blocking / Detection of Phosphorylated Proteins

In immunological detection methods, blocking agents containing phosphoproteins such as skim milk are not well suited for immunoassays with phospho-specific antibodies, and cause high background. Blocking One-P is an exclusive blocking solution, free of phosphate group and endogenous phosphatase. For phospho protein detection. The performance is superior compared with conventional blocking solutions such as 1% BSA. The preservative does not affect the enzyme activity of peroxidase (POD) or alkaline phosphatase (ALP). Only simple refrigerator storage is necessary, even after opening the bottle.

Safe: does not contain phosphorylated proteins

Confirmed: endogenous phosphatase free

High efficiency: more effective than 1% BSA
