GENOME SCANNING SERVICES
Genome Scanning
JAX has developed panels of single nucleotide polymorphism (SNPs) markers that
can be used to confirm strain background, manage backcrossing to create congenic
lines in your facility or monitor the genetic stability of mouse strains. Using a small
sample of DNA from a tail snip or ear punch, we can provide an estimate of the
genetic contributions from two strains within a given mouse.
∙ Standard and custom panels available for comparisons of
most inbred mouse strains.
∙ C57BL/6 substrain characterization panel distinguishes
between C57BL/6J (B6J) and C57BL/6N (B6N) or
C57BL/6NTac (B6NTac) genetic backgrounds.
∙ C57BL/6 vs 129 panel distinguishes between C57BL/6
and 129S.
∙ Custom SNP panel of 150-200 informative polymorphic SNPs
perfectly designed to meet your needs.
∙ Results typically delivered in ~2 weeks.
Overview
∙ Easy to interpret data.
∙ Custom SNP panels available for specific needs.
∙ Increase data reproducibility.
∙ Select breeders to reduce time when making congenic
strains.
Features and Benefits
∙ Start your lines of research with confidence when
importing or sharing mouse lines with collaborators.
∙ Remove the unwanted confound of background
differences when comparing multiple mutations on the
same genetic background.
∙ Confirm the C57BL/6 background of your mice.
∙ Identify breeding mix-ups quickly.
Applications
Considerations
∙ Genome scanning may not help detect genetic drift.
∙ Genome scanning estimates the percent contribution from two
known sources and cannot be used to determine the unknown
background of a mouse strain.
