Protocols

The idenTx chip design is suitable for vasculogenesis assays; however, the detailed protocols for the AIM chips are currently being developed. Please refer to (9) in the publication list below for the protocol to conduct this assay in AIM chips or (3) and (4) papers that used PDMS versions of the chip to conduct this assay.
