As an application of the new model for pooling designs proposed by the last two authors in Guo and Wang (J Combin Theory Ser A 118:2056-058, 2011), we construct a family of pooling designs based on the $t$ -cliques of various sizes of the Johnson graph $J(n,t)$ . Its performance as a pooling design is better than that given in Bai et al. (Discrete Appl Math 157:3038-045, 2009).
