K941514 is an FDA 510(k) clearance for the VENTANA ANTI-S100 PRIMARY ANTIBODY. Classified as Lambda, Antigen, Antiserum, Control (product code DEH), Class II - Special Controls.

Submitted by Ventana Medical Systems, Inc. (Tucson, US). The FDA issued a Cleared decision on April 25, 1997 after a review of 1123 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Immunology FDA review panel, regulated under 21 CFR 866.5550 - the FDA immunology device framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Immunology submissions.
