[Immunodiffusion of non-histone chromosomal proteins from human skin tumors]

A previously unpublished reaction of precipitation in agarose between histone and non-histone proteins extracted in saline buffer from nuclei of human skin tumors, is reported. Two bands of precipitation similar to those in an immunodiffusion reaction between NHP and specific antisera, were observed. The reaction described is very similar to the affinodiffusion reaction of glycoproteins and lectins in agarose.
