Correlation between cytokine concentrations^a

Cytokine	Equation	r	n
IL-4	y = 1.01x − 4.37	0.99	37
IL-6	y = 1.00x − 4.65	0.99	37
IL-10	y = 1.00x + 0.49	0.98	37
IL-12	y = 1.02x + 5.31	0.99	37
IFN-γ	y = 0.99x + 1.66	0.98	37
TNF-α	y = 1,03x + 4.86	0.99	37

^aDetermined by reading the sample against a fresh standard curve (dilution of cytokine standard solutions) or a stored master curve with FMBA for IL-4, IL-6, IL-10, IL-12, IFN-γ, and TNF-α. x corresponds to values determined on a stored master curve, and y corresponds to values determined on a fresh standard curve.
