Cd300lb - Model 8039 - Tg

Random Transgenic

Cryopreserved Model
This line is cryopreserved and requires cryorecovery.

C57BL/6 Background

  • Model #
  • Genotype
  • Nomenclature
  • 8039
  • A plasmid containing the human CMV promoter and a cDNA containing the extracellular domain of Cd300lb (CLM7) fused to a modified IgG domain has been engineered.
  • The plasmid construct was microinjected in C57BL6 mice by pronuclear injection.
  • Putative transgenic founders were identified by genotyping and bred for germ line transmission with C57BL6 mice.
  • Heterozygous transgenic mice were identified by genotyping.
    • Line 8037, C57BL/6-Tg(CD300Ib)12 Mrl

For-profit users: Commercial users may purchase available GEM Collection models by signing the GEM Collection Commercial Terms of Sale and providing a PO. The GEM Collection Commercial Terms of Sale grant perpetual use rights.
Non-profit users: Non-profit users must provide a scientific workplan and execute an MTA prior to accessing a GEM Collection Model.

Non-profit order process is as follows:

  1. Non-profit Investigator visits the Taconic website and identifies GEM of interest.
  2. Non-profit Investigator inquires on Taconic website.
  3. Taconic will answer questions about the GEM lines and the process.
  4. Taconic sends request for MTA.
  5. Non-profit Investigator provides scientific workplan answering 4 basic questions.
  6. MTA is issued for non-profit Investigator/institution review and signature.
  7. MTA is executed by all parties and release of model is approved.
  8. Taconic contacts requestor to obtain purchase order (PO) to cover the cryorecovery and shipment costs.

Taconic begins cryorecovery upon receipt of PO and delivers model to requestor. It is the requestor's obligation to determine that the GEM meets their research needs.

Access to this model for non-profit customers requires approval of a third-party Material Transfer Agreement (MTA). The terms of this MTA are non-negotiable; an example agreement is available so that you may preview the terms. MTA approval may require 4-6 months due to circumstances outside our control. Once approved and the purchase confirmed, order fulfillment will require an additional 14-16 weeks. If you wish to continue your interest in this model, please complete the GEM Collection Inquiry Form. In addition, Taconic also offers complete model generation services that may allow for a reduced timeline to delivery of a comparable model. If you are interested in learning more, please request a GEMs Design Consultation.
GEM Collection models exist as cryopreserved materials. Models can typically be recovered and delivered to customers within 14-16 weeks after order receipt. Customers will receive:

  • A minimum of four (4) mice heterozygous for the selected mutation. In rare cases where the cryopreserved material also contains a recombinase gene, this may be reduced to 1-2 heterozygous mice.
  • Validated genotyping protocols
  • Animal health report. Mice will meet Taconic's Murine Pathogen Free™ (MPF™) health standard.

Please note that in rare instances (2%) cryorecovery may prove to be difficult, either extending timeline or ultimately successful recovery.
