In this congenic strain, the s allele has been introgressed into the BALB/c strain (normally Hbbd). The hemoglobin beta globin allele s occurs naturally in the C57BL/6 inbred strain. Mice with the S haplotype (Hbbs/Hbbs) have two s alleles. Beta globins synthesized from these alleles dimerize and migrate together with alpha globin to form a single band during electrophoresis. The s beta globin is similar to human beta globin, but differs from other mouse beta globins (d, p) by the presence of a single reactive cysteine residue at position 93 (betaCys93). BetaCys93 is involved in nitric oxide metabolism and the formation of mixed disulfides with glutathione and may affect susceptibility to pathogenic infection.
The s allele has been identified as a glycine (GGC) at position 13 and a cysteine at position 93. In contrast, the d allele is comprised of a cysteine at both positions.

Molecular Note | This natural variant identified by protein sequencing, produces a single beta globin with one reactive cysteine (betaCyst13). Two structurally identical beta globins migrate during electrophoresis in a dimer with alpha globin as a single band, therefore the s designation. |

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
