|A time-dependent change in hemoglobin absorbance is|
seen when mixed with the venom for the black-necked
In this application note the spectrometer available on the PHERAstar FS was employed to obtain the absorbance spectrum from 400-700 nm of samples blood samples treated with venom from a variety of snake species. Using BMG LABTECH's ultra-fast spectrometer these readings can be obtained in less than one second per well.
The results showed that characteristic absorbance peaks for blood at 540 and 570 nm were lost in the presence of the venom from some snake species. Furthermore, the effect was time dependent. Based on this and other evidence the observed effect is believed to be enzyme-mediated.
