<p>A soluble, membrane-free and detergent-free interleukin-1 (IL-1) receptor isolated from a human B-cell line is described. The soluble human B-cell IL-1 receptor has an apparent molecular size of about 40 kDa and exhibits at least about a 10-fold greater binding affinity for IL-1β than IL-1α.</p> |
