We raised p75NTR−/− mice in the Wenzhou Medical University Animal Laboratory. The differences in body weights and appearances between p75NTR−/− and p75NTR+/+ mice were compared. Additionally, we dissected the tail tissue for PCR analysis as previously described [17 (link)]. DNA extraction and PCR amplification were using one step mouse genotyping kit (Vazyme, Nanjing, China) according to the manufacturer’s protocol. The PCR products could be observed on a 3% agarose gel containing 5 mg/mL ethidium bromide.
