Assay inactivation due to toxicity and lack of suitable activator

Explains why the mast cell degranulation assay effort was halted ("put on ice"): compound 48/80 is both the only activator inducing β-hexosaminidase release in HMC1.2 and RBL-2H3, but it also causes significant toxicity in these cell models at the same concentrations. No alternative agonist was found that induces degranulation without cell lysis, limiting the ability to test tick anti-inflammatory molecules with this assay.
