The kit is for the quantitative level of SP-D in the sample, adopt purified Human SP-D to coat microtiter plate, make solid-phase antibody, then add SP-D to wells, Combine SP-D antibody with labeled HRP to form antibody-antigen -enzyme-antibody complex, after washing completely, add TMB substrate solution, TMB substrate becomes blue color at HRP enzyme-catalyzed, reaction is terminated by the addition of a stop solution and the color change is measured at a wavelength of 450 nm. The concentration of SP-D in the samples is then determined by comparing the O.D. of the samples to the standard curve. 

DETECTION RANGE
Detection range of the kit is: 0.3ng/L -18ng/L
