Products & CRO/Consulting Services for Multiplex Assay Development
"A-squared technology"
- The A2 (A-squared) "oligo-link" approach enables the creation of multiplex well-based immunoassays without the need to print. Simply couple your antibody of choice to a barcoded oligo using our spin column kit.
- Mix multiple oligo-antibody conjugates together into the hybridization cocktail and deliver to selected wells of the capture oligo A2 plate.
- Hybridization of each conjugate to surface bound complementary capture oligo provides an antibody microarray within one hour ready for assay.
- 100 micro-grams of antibody conjugate can provide 5 or greater 96-well plates depending upon loading and yield.
