Description

【Principle of the method】
Purified anti-human Cystatin C antibody which was coated inpolystyrene particles when mixed with samples containing Cys C,  form insoluble complexes. This complex results in turbidity which will expand with coated polystyrene particles, the turbidity is proportional to the Cys C concentration in the sample. A-muti-level calibration curve is used to determine the rheumatoid factor.
