What is an ATPase Assay for ABC Transporters?
The ATPase assay measures ATP hydrolysis by ABC transporters to identify drug substrates and inhibitors. Learn the method, its uses, and when to choose it over vesicle assays.
What is a Vesicular Transport Assay?
The vesicular transport assay uses inside-out membrane vesicles to measure ABC transporter activity. Learn the method, its regulatory context, and how to choose the right kit.
What is an ABC Transporter?
ABC transporters are membrane proteins that transport drugs and metabolites across cell membranes. Learn their role in DMPK, DDI studies, and drug development.
