Calculations based on an individual blank value

The well-specific absorbance value at 340 nm is subtracted from the corresponding
absorbance value at 260 nm. Then, a value is determined using the corresponding value
for each well used for the sample measurement.

Ext

A1

= (Ext

260 A1

– Ext

340 A1

) – Ext

A1 individual blank value

[OD]

Ext

A2

= (Ext

260 A2

– Ext

340 A2

) – Ext

A2 individual blank value

[OD]

Ext

B1

= (Ext

260 B1

– Ext

340 B1

) – Ext

B1 individual blank value

[OD]

etc.

The absorbance values at 280 nm will also be corrected using the corresponding
absorbance values at 340 nm. The corrected absorbance values will be used to calculate
the 260/280 ratio.
