When a sample of protein solution is applied on the test strip it produces compact and symmetrical protein spots, the diameter of protein spots are proportional to protein concentration. The test kit is supplied with latex protein extraction buffer. After extraction of protein from the latex sample, the extract is applied on the test strip and the test strip is developed to produce protein spots. By measuring the diameter of protein spots with the Protn-Latex™ card (supplied with each kit) you can reliably determine the range of protein concentration in the sample.
