Interrogate IKMC resource No tm1a clones available Nominate for targeting: EUCOMMTools NLAC/NARlabs, Taiwan (20/year) CRISPR/Cas9 in development Production time scales • Each nominated gene passes through many stages before GLT is confirmed Gene nominations from the MMN Production centres expand clones Prepare single cell suspension Grow ES cells after antibiotic selection Transfer embryos to recipient Select blastocyst host with different coat colour Use coat colour to select GA pups Wait for litter to be born >18 months Chimaera mating, confirm GLT, Neo deletion Accessing mice and ex vivo tissues • • • • • • Searching the IMPC website: www.mousephenotype.org Web link takes you to repository holding the mice Alternative alleles/ex vivo tissues may be available Don’t forget to ask! Status of genes nominated for production is also visible Register your interest and get status updates Imports from other production centres • Majority of the MMN lines will be generated in the UK • Other IMPC partners have been assigned MMN genes • We are happy to help acquire mice from around the world International Mouse Strain Resource IMSR Independent labs TIGM RIKEN APF CARD CMMR MMHCC MMRRC EMMA Harwell Jax • >15,000 mouse strains at your finger tips: www.findmice.org European Mouse Mutant Archive (EMMA) • EMMA archives mice generated in Europe www.infrafrontier.eu • Harwell offers a free archiving service High demand from the MMN & others • 177 IMPC mouse lines exported from Harwell • Organs and tissues from 22 strains • 56 investigators from the MMN amongst the recipients • 8 to 10 export requests/week for Harwell mice Measuring impact • Measuring impact - essential but challenging • Repositories track distribution very well • Added value is extremely hard to quantify – grants/publications What do we send out? • Frozen embryos/sperm/live mice – tm1a and tm1b alleles generated for every strain • Conditional allele (tm1c) made to order • Defined tissues/organs harvested from mice on the shelf • MEFs made from homozygous KO mice • Wax embedded slides • Training e.g. Cryocourse (2-5th Mar, 2015) We are here to help: contact us on [email protected]
