Gold colloid and palladium colloid are used as a materials of lateral flow immunoassya and bioassay.
Morinaga Institute of Biological Science, Inc. original colloids are provided with high
concentration, good stability, easy handling and long shelf life.
- 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.
