Cryopreservation and recovery programme for rodents Your valuable genetically altered (GA) strains are best protected against loss through cryopreservation of embryo’s and/ or sperm. The cryo-bank serves as a ‘back-up’ in case of loss of the strain due to breeding cessation, fatal disease, genetic contamination, genetic drift or disaster. Cryopreservation of embryos You provide us with male animals. Three proven transgene transmitting males are already enough. We will mate them with wild type female animals of the right background strain. Cryopreserved embryos are heterozygous if homozygous are supplied or heterozygous and wild type if heterozygous males are supplied. Together with you we decide how many embryos will be stored. However, we advise to at least cryopreserve 250 two-cell stage embryos/ strain. Our quality control programme contains systematic checks throughout the cryopreservation process. These include: test thaws of control embryos and attempts to recover live born mice Cryopreservation of sperm When you choose to freeze sperm only two (transgene transmitting) male mice are needed. At least 20 straws with sperm per strain are stored. We perform a quality control fertilisation test via IVF for every strain. Storage We can store the embryos and sperm at our facility. However, we advise you to at least divide the cryopreserved embryos of one strain over two storage sites, either in your facilities or at our back-up location in Zaltbommel. Recovery programme We will ship cryopreserved embryos and/ or sperm to you upon request. If you want us to do the recovery for you to send you the live animals, we are happy to do that.   Please ask us for a quote based on your needs at info@BioXpert.nl
