Abstract
The present test device provides a merocyanine protein error indicator compound. Merocyanine compounds are a new class of protein error indicators, providing an analytical tool useful in the detection of protein in a sample.
Claims15
An analytical test strip for the detection of protein in a liquid sample comprising an absorbent carrier impregnated with the merocyanine protein error indicator compound:
- ##STR3## wherein:
- m is an integer from 1 to 6;
- Q is --Br, --I, or Cl;
- R is S, Se, O, or C(C.sub.n H.sub.2n+1).sub.2, wherein:
- n is an integer from 1 to 6;
- and
- T is --SO.sub.3 .crclbar. or --H.
4 more elements
A method for the detection of protein in a liquid sample, the method comprising the steps of:
- a) wetting an analytical test strip with the liquid sample, the test strip including an absorbent carrier impregnated with the merocyanine protein error indicator compound:
- ##STR4## wherein:
- m is an integer from 1 to 6;
- Q is --Br, --I, or Cl;
- R is S, Se, O, or C(C.sub.n H.sub.2n+1).sub.2, wherein:
- n is an integer from 1 to 6;
- and
- T is --SO.sub.3 .crclbar. or --H;
- and
- b) observing and recording any color change of the test strip, wherein a color change is indicative of protein in the liquid sample.
7 more elements
A method for the detection of protein in a sample, the method comprising the steps of:
- a) adding to the sample the merocyanine protein error indicator compound:
- ##STR5## wherein:
- m is an integer from 1 to 6;
- Q is --Br, --I, or Cl;
- R is S, Se, O, or C(C.sub.n H.sub.2n+1).sub.2, wherein:
- n is an integer from 1 to 6;
- and
- T is --SO.sub.3 .crclbar. or --H;
- and
- b) observing and recording any color change, wherein a color change is indicative of protein in the sample.
