QuantiQuik™ Pyruvate Quick Test Strips

RT

What samples have you tested?
White wine, beer, serum, plasma, and urine.

How sensitive are the Pyruvate strips?
The Strips can measure levels as low as 50 uM of undiluted pyruvate; however, most samples will require some sort of dilution. The following are the detection limits for samples requiring a dilution:
- Samples requiring a 2x dilution (e.g. serum and plasma): 100 uM, 8.7 mg/L pyruvate
- Samples requiring a 5x dilution (e.g. beer, acidic samples, etc): 250 uM, 22 mg/L pyruvate
- Samples requiring a 9x dilution (e.g. white wine and urine): 450 uM, 39 mg/L pyruvate

My sample turns the strip very dark blue, how can I determine the pyruvate concentration?
Very dark blue indicates that the diluted sample concentration is greater than 1.5 mM (131 mg/L or ppm) pyruvate. To obtain a more accurate concentration, the sample should be diluted and retested. For example, if the sample was diluted 2x, try diluting 5x or 9x. Multiply the concentration of the corresponding color by the dilution factor to determine the pyruvate concentration.

I don’t have access to a pipetteman. How can I accurately measure out my samples?
We offer exact volume transfer pipettes as an accessory. For samples requiring a 2x dilution, order the 400 uL transfer pipettes (TP400). For samples requiring a 5x dilution, order the 100 uL transfer pipettes (TP100). For samples requiring a 9x dilution, order the 50 uL transfer pipettes (TP50).

Can I store unused reagents for future use?
Yes, unused reagents can be stored according to the assay protocol. The strips should be kept in a dry, preferably cool location protected from light.
