Message:

We have some problems with ELISA reader (spectrophotometer): we are not sure if 
filters of 405, 450 and 492 are on right positions.
We measured one sample (of yellow color) at supposed 405, 450 and 492 nm and 
found absorbances: 2,400 ; 1,417 ; 0,829. Is it possible to connect different 
absorbances of the same sample with different waveleghts? For example 
absorbance 2,400 was read at wavelength 450 nm?
With best wishes!
