Strain: iNP/Iusm

Symbol: iNP/Iusm
Strain: iNP
Substrain: Iusm
Full Name: alcohol-nonpreferring
RGD ID: 634381
Citation ID: RRID:RGD_634381
Ontology ID: RS:0000610
Alleles: Npy
Also Known As: alcohol-nonpreferring
Type: inbred
Available Source: Not Available
Origination: Department of Medicine, Indiana University School of Medicine, Indianapolis, Indiana
Description: These were inbred alcohol-nonpreferring rats developed from outbred alcohol-nonpreferring rats (Iusm:NP) at generation 30 at Indiana University for high-alcohol-nonpreferring behavior. Inbred rats utilized for the development of alcohol-preferring, alcohol-nonpreferring congenic strains were in the27th generation of inbreeding.
Last Known Status: Unknown
