Technical note

- Small amount of buffer is enough to adjust pH when antibodies are combined to colloid particles.

- Multi-assay is available by using both Gold Colloid AuH1 (red color) and Palladium Colloid Pd1 (black color) .

- Colloid particles have minus charge so as not to avoid agglutination.
