Sinclair Bio Resources assumed production of one colony from Biotech in 1995 and one colony from Charles River Laboratories in 2002
The former Biotech colony is located in Auxvasse, MO and the former Charles River Laboratory colony is in Windham, ME
The colonies are closed and fully pedigreed

Ventricular Septal Defect (VSD) lineage available
