Patents on Measuring cfDNA to Detect Rejection of Transplanted Organs Held Invalid | Insights

When a person who has received an organ transplant experiences rejection, DNA from the transplanted organ is released into the bloodstream as the organ’s cells are attacked by the person’s immune system. The circulating DNA from the transplanted organ — referred to as cell-free DNA (cfDNA) — can be distinguished…

C698R mutation in Lrsam1 gene impairs nerve regeneration in a CMT2P mouse model

Animal generation The Lrsam1C698R knock-in mice were generated on a C57Bl/6J background using the CRISPR/Cas9 technique. Briefly, single-cell zygotes from C57BL/6J mice were microinjected with mRNA encoding Cas9 and a guide sequence (5′-ACAGCAGCAGACGTGGCCAC-3′ at 20 ng/µl) to target the exon 26 of Lrsam1. A single stranded DNA oligo carrying the C698R mutation…
