Principle of Assay
Ochratoxin A Strip Test Kit (A327237) uses a competitive colloidal gold based format. The sample is added to the test well to allow the Ochratoxin A binding protein on the gold particles to engage with any Ochratoxin A present in the sample. Any gold particles that are not complexed with Ochratoxin A present in the sample will bind to the Ochratoxin A imprinted at the Test line (T-line), forming a signal (red line) at that position. If the Ochratoxin A binding protein on the gold particle has engaged with Ochratoxin A present in the sample, the gold particle will flow past the T-line and reach the Control line (C-line).
