ABSTRACT:
A test/control procedure and material is provided to facilitate standardization of immunostaining techniques and the assessment of their results. Pellets of an absorbent gel such as agar gel are caused to adsorb individual specific concentrations of an antigen of interest. The adsorbed antigens are confined to the individual pellets as by fixation or by enclosure in a diffusion-inhibiting barrier, and the pellets are installed in individual wells in a block of the gel in a manner to become integrated therein. The block may then be subjected to the same preparative routines as a tissue sample, sectioned and mounted like the sample, and then subjected to immunostaining by the same routine as the sample sections to provide a valid basis for assessment of the stained sample sections by comparison with the stained gel block sections. A gel block of suitable configuration is also disclosed.
