Lysate Kinase Activity Assays

PhosphoSens Lysate Assays directly quantify functional kinase activity in cell and tissue lysates. Unlike phosphoprotein methods that only measure phosphorylation state as a proxy, PhosphoSens captures true enzymatic activity at the substrate level, delivering real-time progress curves in a biologically relevant context.

Every well produces a complete activity profile — not just a snapshot — so you can clearly see kinase function, inhibitor dynamics, and pathway modulation in the context of native biology.

Phosphorylation ≠ Activity

Most kinase assays infer activity from phospho-status. Learn why catalytic function and phosphorylation often diverge — and how PhosphoSens measures real activity.
