Nonallelic behavior of rabbit variable-region allotypes.

Nonallelic behavior of rabbit variable-region allotypes

Group a allotypes not detected by qualitative typing or anticipated from breeding data (latent allotypes) were detected at low levels in 50% of normal rabbit sera tested. The latent allotypes, which were serologically identical to allotypes of pooled IgG, were detected in sera from rabbits with all possible combinations of group a allotypes and their occurrence in individual rabbits was transit...

ISOLATION AND CHARACTERIZATION OF IgG MOLECULES EXPRESSING LATENT GROUP b ALLOTYPES FROM PEDIGREED b4b

Genetic studies have indicated that immunoglobulin allotypes are inherited as codominant Mendelian alleles and that their synthesis is controlled by genes at three unlinked loci (1). However, recent evidence has challenged the notion that immunoglobulin allotypes are encoded by allelic structural genes, and has led to the suggestion that individuals may possess complex groups of structural gene...

Immunoglobulin allotypes of rabbit kappa chains: polymorphism of a control mechanism regulating closely linked duplicated genes?

The amino acid sequence of the constant (CK) region from the kappa immunoglobulin chains of a b9 rabbit is compared with the CK sequences, taken from the literature, of a b4 rabbit. These CK regions differ by 33% of their amino acid sequences and by three sequence insertions or deletions (sequence gaps). These extensive differences together with other published observations suggest that the b9 ...

extremal region detection guided by maxima of gradient magnitude

a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
