Fig. 1. Analysis of MHC-A and MHC-B expression in TSU-pr1. Immunoblots of TSU-pr1
cell extracts immunoprecipitated with antibodies against either MHC-A or
MHC-B, or both, were electrophoresed as described (Kelley et al.,
1996). Extracts of RBL and COS
cells electrophoresed in 7% SDS-PAGE. The proteins were transferred to
nitrocellulose membranes and were probed with an antibody specific to either
MHC-A or MHC-B, or with both.
