International strain name	C57BL/6N-Lepr^{tm1a(EUCOMM)Wtsi}/H
Alternative name	EPD0548_5_G08
Strain type	Targeted Mutant Strains
Allele/Transgene symbol	Lepr^{tm1a(EUCOMM)Wtsi}
Gene/Transgene symbol	Lepr
Disclaimer	Please note that for EUCOMM and KOMP-CSD mice supplied to the scientific community by INFRAFRONTIER/EMMA: We can not guarantee a null mutation for Knock-out first alleles (tm1a alleles, see http://www.mousephenotype.org/about-ikmc/targeting-strategies) as the critical exon has not been deleted. That the structure of the targeted mutation in the ES cells obtained from EUCOMM/KOMP to generate EUCOMM/KOMP mice is not verified by INFRAFRONTIER/EMMA. It is recommended that the recipient confirms the mutation structure. No check for determining the copy number of the targeting construct in ES cells obtained from EUCOMM/KOMP is done by INFRAFRONTIER/EMMA. The level of quality control before mice are released is to confirm the individual mouse genotype by short range PCR.
