Abstract

The invention discloses a preparation method and application of a ready-to-use antibody reagent (immunohistochemical), and relates to the field of pathological detection reagents. The universal antibody diluent comprises a biological buffer solution, a protein protective agent, a protein stabilizer, a polymer accelerator (sensitizer), a protein dispersant, an efficient protease inhibitor, a preservative and the like, so that the universal antibody diluent has the characteristics of high sensitivity, low background, clear dyeing and long period of validity.

Description

technical field [0001] The invention relates to the field of pathological detection reagents, in particular to a preparation method and application of a ready-to-use antibody reagent (immunohistochemistry). Background technique [0002] Immunohistochemistry (IHC) is an indispensable and important technical means in the current pathological diagnosis process, and has played an immeasurable role in tumor diagnosis, typing and identification, guiding medication, prognostic evaluation and efficacy evaluation. [0003] Six kinds of antibodies including TOP2A, P27KIP1, GST-pi, EpCAM, Podoplanin, and VEGFA are contained in extremely small amounts in ready-to-use antibody reagents (immunohistochemistry), and are very unstable when using traditional antibody diluents to prepare antibody reagents. Ready-to-use antibody reagents (immunohistochemistry) have a very short shelf life. [0004] Ready-to-use immunohistochemical antibody (protein) reagents generally exist in the form of solu...
