Kcnj12 Knockout mouse models
Kcnj12, the mouse ortholog of human KCNJ12, encodes Kir2.2, a strong inward rectifier whose rectification arises from voltage-dependent block of the pore by intracellular magnesium and polyamines binding at a conserved aspartate in the second transmembrane segment and at cytoplasmic domain residues. Kir2.2 requires PIP2 for opening, and the crystal structures of this channel defined the PIP2 binding site for the entire Kir2 family. Functionally it co-assembles with Kir2.1 and Kir2.3 to build the cardiac and neuronal IK1 conductance that stabilizes resting membrane potential and sets the final phase of repolarization, and it is expressed in ventricular myocytes, skeletal muscle, and brain. Because heteromerization with the Kcnj2 and Kcnj4 products is the rule rather than the exception, single-locus nulls are typically viable with modest current reduction, and dominant-negative pore knockins or compound conditional alleles are needed to collapse IK1. Choose conditional deletion with cardiac or neuronal Cre when attributing arrhythmia or excitability phenotypes.
Whole body loss of Kcnj12 gives the clearest readout when the question is whether the gene is required at all. Follow up tissue work can still move to a conditional allele if lethality or compensation appears.

Why this approach
A conventional knockout answers whether the gene is required broadly. When your target tissue is the organ of interest, a global null can still be informative if viability is acceptable and you want the simplest genotype. If the null is harsh, a floxed allele with a regional Cre is the safer long term platform.

FAQ
What Kcnj12 Knockout mouse models are available?
When Kcnj12 Knockout lines are in catalog, we ship from inventory. If your configuration is not listed, we design the allele to order. Common paths include conditional knockout, constitutive knockout, humanized, knockin, and transgenic options, with documented germline transmission and United States QC.
Is Kcnj12 knockout embryonic lethal in mice?
It depends on background and allele design. Some Kcnj12 germline knockouts are viable. Others need conditional alleles or mixed backgrounds. We review publications and our own experience, then recommend floxed versus null before you commit.
Which Cre driver is best for experiments?
Driver choice depends on onset timing, recombination efficiency, and known leak. We map your organ and cell type to a short list of proven Cre lines, then talk through reporter crosses and controls. We favor drivers with strong community validation for your tissue.
Do you ship live Kcnj12 animals?
When catalog lines are live, we ship with health certificates and QC documentation. If your exact combo is not listed, we quote a generation project with cryo or live dispatch depending on cohort timing and geography.
How do I request a quote for Kcnj12?
Use the catalog inquire buttons or the request quote form. Include your allele goal, Cre plan if any, strain background, and cohort size. A PhD led team responds with pricing, milestones, and the fastest path to experimental animals.
