Fig. 2From: Improving the diagnosis of active tuberculosis: a novel approach using magnetic particle-based chemiluminescence LAM assayForteBio Octet determination of the affinities of the (A) LD9E3 and (B) LD7C1 toward LAM. A sensorgram showing LAM on the aminopropylsilane sensors binding to different concentrations of rabbit mAbs. Saline buffer was used as the negative control. The binding affinity parameter KD was calculated. R2 is the coefficient of determination for estimating the goodness of the curve fit, as reported by ForteBio Data Analysis Software 9.0Back to article page
