Laragen Mouse Genotyping Services

Laragen's unique knowledge and experience with Mouse Genotyping stands us apart from others. The outstanding service with standard turnaround times of just 48 hours, combined with special same day service upon request, insure you will get your results when you need them. And you can count on the results with our 99.95% accuracy.

We require 0.3 to 0.4 cm tail clips or 2 mm ear punches. It is important that the tissue samples have similar sizes. Samples can be sent in either 1.7 ml Eppendorf tubes or 1.1ml 8-strip microtubes in 96 well boxes.

Samples in 96-well plate format should be arranged by the columns as indicated below:


Depending on the number of samples and nature of the tests, we either waive the initial set-up fee or only charge a nominal set-up fee to cover the reagent cost. For the mouse models that are not in the Laragen test pool, we need to have the following to develop and convert to the Laragen mouse genotyping protocols:

  • Existing mouse genotyping protocols
  • Transgene construct sequences
  • Transgenic integration site or knock-in/knock-out sites if possible
  • Control samples to validate the tests

Probe Based TaqMan Mouse Genotyping Service

Most of Laragen’s mouse genotyping tests are probe-based TaqMan assays. Laragen’s TaqMan assays have an internal positive control on a housekeeping gene to ensure the test integrity. Besides all tests also have CAR(carrier) (HOMO and HET, if applicable), WT(wildtype) and NTC controls. The samples in the grey zone will be repeated multiple times to ensure test accuracy, free of charge.

Gel Based PCR Mouse Genotyping Service

A small portion of Largen’s mouse genotyping tests are gel based PCR assays. Like probe-based assays, we also include an internal positive control PCR on a house-keeping gene to ensure PCR integrity. All PCR reactions are optimized to yield accurate genotyping results even at suboptimal conditions. A vigorous SOP is implemented to eliminate PCR contamination problems.

Heterozyogsity Mouse Genotyping by TaqMan Service

Laragen also provides heterozygosity tests for transgenic mice based on qPCR (TaqMan) via copy number analysis. Normalized high quality genomic DNA samples are tested in triplicates and the transgene copy number of unknown samples are compared with the known het and homo controls.

SNP Genotyping Service

Laragen offers low to medium throughput SNP genotyping by the following two platforms:

  • SNP genotyping by re-sequencing analysis
  • SNP genotyping by TaqMan allelic discrimination analysis
Depending on your projects, we will help you to design a suitable SNP genotyping methodology.
