HLA-DR typing: a comparison between nylon wool adherence and T cell rosetting in the isolation of B cells.

A comparison was made between two different methods of B cell isolation, nylon wool adherence versus SRBC rosetting in terms of the technical ease of B cell purification and the reproducibility of DR phenotyping. It was found that B cells isolated by either method from 30 randomly selected donors gave equivalent results in the determination of DR phenotypes. Due to its simplicity and reliability, nylon wool adherence may be preferred over the SRBC rosette method for the routine phenotyping of B cells.
