Mouse genotypes were confirmed by PCR42 (link),43 (link). Genomic DNA was isolated from tail snips using a Maxwell tissue DNA kit (Cat# AS1030, Promega, Madison, WI). miR-146a genotyping was performed using the following primers: 5′-GCTTATGAACTT GCCTATCTGTG-3′ and 5′-CAGCAGTTCCACGCTTCA-3′. PCR of wild-type and disrupted alleles generated amplicons of 350 bp and 159 bp, respectively. A representative gel of miR-146a+/+ and −/− amplicons is shown in the Fig. 1C42 (link),43 (link).
