Temporary Suspension of International Shipping of Live Animals
 July 08, 2024
Effective immediately: Due to continued weather-related issues negatively impacting the safety, reliability, and cost of shipping, we are temporarily suspending international shipments of live animals.   Orders may still be placed but they will not be filled until after September 1, 2024. We apologize for any inconvenience and thank you for your understanding.

Weather and high temperatures are also affecting domestic shipping so expect delays. The welfare of the animals is our top priority. 
Laboratory Animal Genetic Reporting (LAG-R) Guidelines Published
 July 07, 2024
The LAG-R framework (Laboratory Animal Genetic Reporting) is a set of guidelines to support more complete documentation of the genetic make-up of animals of all species that are used in research, with the aim of bolstering reproducibility, reliability, and overall scientific rigor.

GRCr8 (GenBank NCBI # GCA_036323735.1) is the latest version of the rat reference genome assembly. See the Genome Reference Consortium (GRC) blog for more details.
Happy World Rat Day!
 April 04, 2023
April 4, 2023 is World Rat Day!  The RRRC would like to acknowledge the important contributions to science and medicine made possible by the use of rats in biomedical research.
The RRRC has developed a number of diagnostic tests and techniques for utilization in genetic testing for rats.  These tests include methods for the detection and identification of chromosomal integration sites and microsatellite markers panels for genetic monitoring of common rat strains.
