Inbred Strains of Mice: AL


Inbr: F166. Albino. Genet: a, b, c. Believed to have originated from an illegitimate mating of strain A followed by b x s mating, but should not be considered as a substrain of strain A. Very low mammary tumour incidence (Staats, 1976).

Normal physiology

High erythrocyte catalase level (3/18) (Hoffman and Rechcigle, 1971).


Phenobarbital i.p. does not induce hepatic epoxide hydrase (cf. 3/7) (Oesch et al., 1973., 1973). Long hexobarbital sleeping time (9/9) and low liver hexobarbital oxidase level (1/9) (Vesell, 1968).


Resistant to the induction of liver amyloid, but a high level of spontaneous amyloidosis (10/10) (Ram et al., 1969., 1969). Low susceptibility to induction of amyloid (6/6) (Willerson et al., 1969., 1969). Good immune response to synthetic double-stranded RNA (1/7) (strain quoted as ALN, but presumed to be AL/N) (Steinberg et al., 1971., 1971). Poor immune response to Vi antigen (cf. 3/5) (Gaines et al., 1965., 1965). High anti-DNP antibody concentration (1/7) (Paul et al., 1970., 1970).


Good breeding performance with 2.3 young per female per month (5/24) (Hansen et al., 1973., 1973).


AL/N has only 38 chromosomes, including two translocation submetacentrics involving Robertsonian translocations of chromosomes 5 and 19 (White and Tjio, 1975).
