Elisa Ann 🆒 🆓

In a traditional ELISA, a solid surface like a polystyrene plate is used to immobilize antigens or antibodies. In P-ELISA, or cellulose surfaces replace these plates, offering several advantages:

: It uses tiny reagent volumes—often as low as 3 µL —and eliminates the need for expensive laboratory readers, as results can often be scanned with a smartphone. elisa ann

: The high surface-to-volume ratio of cellulose fibers significantly reduces reaction times, allowing tests to be completed in under an hour (compared to 4–6 hours for conventional methods). In a traditional ELISA, a solid surface like
