The β₁ and β₂ proteins from LADV cells are of expected size.

(A) LADV cells and control lymphoblastoid cells were lysed and proteins in the lysates were immunoprecipitated with the anti-β₂, mAb 60.3, or with an irrelevant control antibody, anti-CD14. The proteins were then separated on a 7.5% SDS-PAGE gel, transferred to a nitrocellulose membrane, and Western blot analysis was performed using the anti-β₂ mAb 60.3. Equal amounts of protein were applied to each lane. The β₂ protein band immunoprecipitated from LADV cells is of identical size and is at least as intense as that from control cells. (B) Transformed LADV cells, control lymphoblastoid cells, or Jurkat T cells were lysed, the proteins were separated on a 7.5% SDS-PAGE gel under nonreducing conditions, and analyzed by Western blot, using the anti-β₁ mAb 13. Although there are variations in loading, the proteins from each cell type are of similar size.
