Circulating IgG from patients with sarcoidosis binds to recombinant mKatG and mHsp65 protein. Protein immunoblots with recombinant mKatG (A) or mHsp65 (B) were analyzed with IgG purified from the sera of healthy PPD (N), PPD+ (P) subjects or sarcoidosis (S) patients corresponding to Table IV. Arrowheads demark migration of mol wt markers (top to bottom: 188, 62, 49, and 38 kD). Arrows demark ∼80- and ∼60-kD antigenic bands reactive to mKatG or a 65-kD band reactive to mHsp65.
