Establishment of primary chicken embryo myoblast cell culture, antigenic epitopes prediction and production of anti activin receptor type IIB polyclonal antibody in chicken.

The detection of activin receptor typeIIB ( protein, a prominent negative muscle growth regulator has paramount value in augmenting growth traits through molecular breeding schemes in chicken. The study was formulated to establish primary chicken embryo myoblast culture (CEM) using 9th and 18th day chick embryos and to develop antibodies for immunodetection of protein. The physicochemical and structural attributes of the sequence were evaluated to identify substantial antigenic regions.

Genetic diversity at major histocompatibility complex and its effect on production and immune traits in indigenous chicken breeds of India.

The genetic diversity at major histocompatibility complex (MHC) in indigenous chicken breeds of India (Ghagus and Nicobari) in comparison with the White Leghorn (WLH) breed was investigated by genotyping the MHC-linked LEI0258 marker. Altogether 38 alleles and 96 genotypes were observed among three breeds. The observed and effective alleles were highest in Ghagus (23, 8.

Genetic polymorphism in core promoter sequence of ACTRIIB gene and association analysis with growth traits in chicken.

Molecular breeding exploiting candidate genes is burgeoning reproductive approach to improve growth traits in poultry. The activin type IIB receptor (ACTRIIB) is a negative growth regulator, modulating action of many muscle growth regulators. PCR-single-strand conformation polymorphism was employed to unravel polymorphism in promoter region of the ACTRIIB gene and delineate its association with growth traits in Aseel and control broiler (CB).

Molecular characterization and expression profiling of BMP 3 gene in broiler and layer chicken.

A study was carried out to characterize and explore the expression profile of BMP 3 gene in control broiler and control layer chicken. The total open reading frame of BMP 3 (1389 bp) was cloned and sequenced. The control broiler and control layer chicken showed variation at nucleotide and amino acid level with reference gene (Gallus gallus, NCBI Acc.
