Spr baseline shift
Web11 Jan 2024 · In general, prime the system after each buffer change and wait for a stable baseline. Failing to equilibrate the system will result in a waviness pump stroke because the previous buffer is mixing with the next buffer in the pump. After some pump strokes the signal will be stable again. Web5 Aug 2014 · This SPR baseline shift indicates that VEGF released from SKOV-3 cells has bound to the VEGFR.
