Cystatin C adsorption inhibitor |
摘要 |
Disclosed is a method by which the adsorption of cystatin C to a container can be inhibited in a simple manner to improve the accuracy of the measurement of cystatin C. Provided are: a cystatin C adsorption inhibitor comprising a non-ionic surfactant; a cystatin C measurement reagent comprising the adsorption inhibitor; and a cystatin C measurement kit. Also provided is a method of inhibiting the adsorption of cystatin C, the method comprising bringing a cystatin C-containing sample into contact with a measurement instrument in the presence of a non-ionic surfactant. The aforementioned non-ionic surfactant is preferably a polyoxyethylene-type surfactant. Alternatively, the aforementioned non-ionic surfactant has preferably a phenoxy structure, more preferably a benzylphenoxy structure. |

1. A method of improving the measurement of cystatin C in a sample, said method comprising:
inhibiting the adsorption of cystatin C to a measurement instrument comprising bringing a cystatin C-containing sample into contact with the measurement instrument in the presence of a non-ionic surfactant, wherein said non-ionic surfactant is selected from the group consisting of polyoxyethylene distyrenated phenylether, and polyoxyethylene tribenzylphenylether and measuring the amount of cystatin C in the sample. |
