Fibroblast-like synoviocytes from patients with rheumatoid arthritis (RA-FLS) express proteins of multiple calcium-activated potassium channel KCa1.1 β subunits. a Representative Western blot from a gel loaded with proteins from one RA-FLS donor with different lanes probed with antibodies against different subunits of KCa1.1 (top) and actin (bottom). b Intensity of KCa1.1 α and β subunit protein bands normalized to actin expression levels in RA-FLS. Each symbol on the scatterplot represents results from a different donor. The horizontal bar represents the mean for each subunit
