K14-CreERT2 for skin conditional models
Conditional deletion of Target limits genetic change to the lineage you choose. That precision matters for oncology, immunology, and metabolic work where systemic loss would confound interpretation. After you confirm your Cre specificity, crossing to Target floxed stock yields interpretable cohorts. For skin work, plan Cre specificity, reporter crosses, and baseline phenotyping before you scale.
Driver pairing notes
K14-CreERT2 biases recombination toward skin lineages. Inducible design: yes, via tamoxifen.
Conditional knockout keeps skin as the experimental theater while the rest of the animal retains a wild type allele. That pattern mirrors somatic mutation in patients and avoids systemic compensation that can erase subtle phenotypes. It is often preferred when a germline null is lethal, weak, or confounded by developmental rescue.
A conventional knockout answers whether the gene is required broadly. When skin 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.

Frequently asked questions
What animals express K14-CreERT2?
K14-CreERT2 is used for skin biased recombination in community standard protocols. We recommend reporter validation on your background before large experiments.
Is K14-CreERT2 inducible?
Some lines in the CreERT2 family need tamoxifen for nuclear access. Tell us your timing goals and we help pick tamoxifen versus constitutive strategies.
Which floxed genes pair with K14-CreERT2?
Top pairs depend on your disease model. We link common conditional alleles in our catalog and can suggest three to five references genes that match skin biology.
