|**This cell line is a cluster knockout in which more than one gene has been targeted**|
Gene Symbol: Mir23b
Name: microRNA 23b
Alteration at locus: Knockout
Gene Symbol: Mir27b
Name: microRNA 27b
Alteration at locus: Knockout
The cluster of microRNA genes was replaced via homologous recombination by a LoxP-F3-PGK-EM7-PuroΔtk-bpA-LoxP-FRT targeting vector with 5.5kb (5’) and 3.3kb (3’) arms of homology. Briefly, this is a puromycin/thymidine kinase fusion gene under the control of EM7/PGK promoters and flanked by LoxP and F3/FRT sites. Schematic of MirKO targeting vector and alleles

Requested cell lines are tested by PCR analysis for mycoplasma spp. and Murine Parvoviruses (MPV) upon completion of expansion and prior to shipment. Mice derived from requested cell lines via Microinjection services will be pathogen tested prior to delivery of mice and health reports will be provided. If you require additional health status information prior to requesting microinjection please email firstname.lastname@example.org.
Cryo-preserved ES cell line material can usually be shipped in 2 to 4 weeks. Genetic confirmation adds an additional 4 to 6 weeks (but is recommended to confirm that the material has not been contaminated or otherwise incorrectly identified). The microinjection services add an additional 10 to 12 weeks and can vary from cell line to cell line.
Please complete the MMRRC Conditions of Use (COU) and provide it at the time your order is placed. Note: The preceding link is to the COU text only; the COU user form will be provided after order submission.
Additional charges may apply for any special requests. Shipping costs are in addition to the basic distribution/resuscitation fees. Information on shipping costs and any additional charges will be provided by the supplying MMRRC facility.

Fee/unit (US $)
|Vial||Without sequence confirmation.*|
|per cell line||Genetic confirmation recommended.*Service fee is in addition to fee for mutant cell line.|
|per cell line||In addition to the per mutant ES cell line fee (see above); chimeras not guaranteed.|
*Genetic confirmation of a cell line is an add-on service; cost is in addition to the cost of the cell line itself. We recommend minimum verification of the cell line by genetic confirmation of the reporter sequence. Please inquire with the supplying MMRRC facility when ordering (email@example.com).
