Igf2 Knockout mouse models
Igf2 is the mouse ortholog of human IGF2 and encodes a fetal growth factor whose expression is paternally monoallelic under control of the H19 imprinting control region through CTCF-dependent enhancer competition, with additional input from intragenic differentially methylated regions. The mature peptide signals through IGF1R and, distinctively, through the insulin receptor A isoform, while IGF2R clears it from circulation, making its dosage unusually sensitive to both imprinting status and receptor stoichiometry. Human loss of imprinting drives Beckwith-Wiedemann overgrowth and Wilms tumor, whereas hypomethylation reduces growth in Silver-Russell syndrome, a bidirectional disease logic that allele design should mirror: a paternal-allele conditional null tests the growth requirement, imprinting control region deletion or targeted methylation alleles model biallelic expression, and humanization supports antibody or ligand trap testing. Because Igf1 covers much of postnatal growth, phenotypes concentrate prenatally. Match allele to embryonic and placental growth measurement, allele-specific expression assays, and tumor incidence.
A conventional Igf2 knockout removes gene function in all cells that inherit the allele. It is a proven first pass for target validation when redundancy is low.

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 Igf2 Knockout mouse models are available?
When Igf2 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 Igf2 knockout embryonic lethal in mice?
It depends on background and allele design. Some Igf2 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 Igf2 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 Igf2?
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.
