Application

EIA (1:1,000)r>Tissue Staining (1:50 - 1:100)

General description

Avidin (and streptavidin) has 4 binding sites for biotin. Taking advantage of the high affinity between avidin and biotin, this fluorescein-conjugated biotin-X (a 6-atom spacer) provides a method for fluorescent detection of biotinylated antibodies.

Make a stock solution by dissolving in DMF (DMSO and methanol should also work). Suggested concentration for stock solution is 5 mg/ml. Dilute stock solution with appropriate buffer for assay just prior to use. For tissue staining, suggested usage is to dilute stock solution to 1 mg/ml and then dilute that solution 1:50 - 1:100. For EIA, follow the same procedure, but dilute the 1 mg/ml solution 1:1,000. Variables associated with assay conditions will dictate the proper working dilution.

Packaging
