Higher sensitivity | IL-6 & TNF- α low detection rate how to do?

      The detection of cytokines is mainly divided into three detection methods: immunology, biology and molecular biology. Immunological method is mainly measured by double anti-sandwich ELISA. Cytokines are known to be extremely low (mostly at pg/ml level). Routine ELISA kits on the market often fail to meet the detection requirements of low concentration samples, and may have low signal or no signal.
