In 2025, 37 % of pharmaceutical R&D projects missed milestones because the critical reagents used in receptor‑binding assays were either impure, inconsistently supplied, or arrived after the required experimental window. Below are the three most common pain points you probably recognize:
Imagine a scenario where you must repeat a critical NMBR BB1 pull‑down assay because the batch you received showed 12 % lower activity. That means extra labor, additional consumables, and a delayed decision on lead optimization—costs that quickly add up to **$150 k** per project.
