Signal to background ratio assay
WebAttention to raw materials, cleanliness of mixing and storage vessels and buffer preparation methods should reduce this to acceptable levels. High background counts due to buffer or non-fluorophore components can seriously affect the signal-noise ratios of an assay as well as the ultimate sensitivity of an assay. 2d. Avoid bovine serum albumin. WebThese intricacies can lead to a failure to produce an ELISA signal; optimization of an assay is essential. ... Too little enzyme and the signal may be very weak with a poor signal-to-noise ratio. Too much and the background may be too high, again resulting in a poor signal-to-noise ratio and little distinction between standards of different ...
