*** HINT: To calculate [ONPG], cuvette #5 contains 1.0mL ONPG in a total of 2.0mL. (This is the same as a 1:2
dilution.) Therefore we divide the concentration of ONPG by 2 to get 5mM.

4. To perform Lactase Assay with first cuvette ("OmM"):
Clean cuvette with Kimwipe.
Place cuvette into Spectro Vis with stripes in front in back.
GET GROUP READY FOR TIMED ASSAY. AT THE SAME TIME:
* Press Record (Green Triangle button).
* Add 0.25mL of Lactase to cuvette. Use pipette to quickly mix liquid.
WAIT 60 SECONDS! After the assay is complete:
* In Experiment menu, select "Store Latest Run" THIS STEP IS NECESSARY!
* Record data on the data table below.
5. Repeat Step 7 for all of your cuvettes. Record…
