  • Title: An improved micro-method for avidin assay.
    Author: Elo H, Tuohimaa P.
    Journal: Biochem J; 1974 Apr; 140(1):115-6. PubMed ID: 4451549.
    Abstract:
    A sensitive method for avidin assay was devised. Tritiated biotin is bound to avidin and this complex is then bound to bentonite. Radioactivity is converted into a gas form by combustion and counted in an automatic proportional counter with 55% efficiency and background of 3.7c.p.m. The sensitivity is 1-2ng of avidin.
