TEST STRIP FOR SHORT-WAVE NEAR INFRARED IMMUNOFLUORESCENCE CHROMATOGRAPHIC DETECTION AND USE THEREOF

摘要

Provided are a test strip for short-wave near infrared immunofluorescence chromatographic detection, a system for immunofluorescence chromatographic detection and a method for quantifying an analyte in a sample. The test strip for short-wave near infrared immunofluorescence chromatographic detection includes: a body, defining a sample region, a binding region, a detecting region and an adsorbing region connected with one another sequentially; a first antibody, labeled with a fluorescent microsphere, coated on the binding region and configured to specifically recognize an analyte; a detecting line and a quality control line, located in the detecting region, wherein the detecting line closes to the binding region; a second antibody, coated on the detecting line and configured to specifically recognize the analyte; and a third antibody, coated on the quality control line and configured to specifically recognize the first antibody, in which the fluorescent microsphere is a near-infrared II polymer fluorescent microsphere.
