Figure 1. Similar relative amounts of μ- and m-calpain in resting CD4⁺ and CD8⁺ lymphocytes.

Calpain amounts were estimated by flow cytometry using appropriate anti-calpain and anti-calpastatin antibodies as well as appropriate surface staining as in Materials and Methods. CCS protein amounts are shown for each individual (•) and as means ⁺/− SD. Statistical significance of differences was assessed using unpaired T test. The differences were not statistically significant (n.s). N = 12.
