Binding of stimulated human peripheral blood lymphocytes to sepharose-concanavalin A is not reversed by methyl-. cap alpha. -mannoside
Concanavalin A (con A) bound to Sepharose beads stimulates human peripheral blood lymphocytes and as with soluble con A, DNA synthesis can be prevented by the addition of methyl-..cap alpha..-mannoside (MAM) 1 hr after exposure to mitogen. In contrast to the response of cells stimulated with soluble con A, addition of MAM 24 hr after the start of incubation with Sepharose bound mitogen does not prevent a second round of DNA replication as determined in bromodeoxyuridine density transfer experiments indicating that MAM does not dissociate the Sepharose-con A responding cell complex. We infer that within 24 hr, lymphocytes develop associations with con A-Sepharose beads at non MAM dissociable sites.
