Vitamin B12 Lateral Flow Assay.

(A) Strip image and schematic of the custom B12 test strip architecture and components (B) Competitive interaction between the sample B12 and bound BSA-B12 at test line for a limited binding regions on AuNP-anti-B12 results in a weak T/C signal intensity for high B12 in the sample and (C) strong T/C signal intensity for low B12 in the sample.
