Albumin-Cre for liver conditional models
Tissue restricted knockout of Target reduces off target stress compared with constitutive loss. You retain wild type Target everywhere else, which improves breeding robustness and mirrors patient biology where mutations arise in a subset of cells. For liver work, plan Cre specificity, reporter crosses, and baseline phenotyping before you scale.
Driver pairing notes
Hepatocyte directed Albumin promoter driven Cre. Widely used for liver specific recombination with minimal reported extrahepatic activity in most Cre reporter studies. Pair with floxed alleles for late stage metabolic and oncology experiments.
Conditional knockout keeps liver 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 liver 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 Albumin-Cre?
Albumin-Cre is used for liver biased recombination in community standard protocols. We recommend reporter validation on your background before large experiments.
Is Albumin-Cre 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 Albumin-Cre?
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 liver biology.
