Beta-lactoglobulin polymorphism in Girgentana goat breed

Genetic polymorphism at the CSN1S1 gene in Girgentana dairy goat breed

The aim of this work was to evaluate the variability of the as1-casein locus in the endangered Girgentana dairy goat breed in order to define genetic improvement and a conservation program for this breed. The study was performed on 200 dairy goats by means of different PCR protocols. Themost frequent alleles were A (0.590) and F (0.290) followed by B (0.065) and N (0.047).CSN1S1 E allele was id...

Polymorphism of Beta-lactoglobulin Gene in Select Population Slovak Spotted Breed

The goal of the paper was to identify  lactoglobulin gene polymorphism and analyse of genotype structure in population Slovak spotted breed. The  lactoglobulin (LGB) expressed in milk and is important in the evaluation of milk production potential and butterfat and protein content. LGB is localized on bovine chromosome 11. The AA genotype of LGB is associated with higher milk yield, the BB ge...

Crystallization of Goat p - Lactoglobulin

as 'goat lactoglobulin' gave a single peak on electrophoresis at pH 8.0 in barbiturate buffer, but three boundaries separated at pH 7-0 and at least two at pH 4-2-6-0 after 2 hr. at 4-5 v/cm., I= 01. The two main components had their isoelectric points at pH 5-2 and 5-9 respectively in sodium acetate buffer, I= 0-1. 'Goat lactoglobulin' thus behaved in much the same way as crystalline bovine ,B...

Rapid communication: Polymorphism in the goat β-lactoglobulin proximal promoter region1

Polymorphism. Polymorphism was detected within a 710-bp-long PCR amplification product of the goat βlactoglobulin (BLG) gene, comprising 588 bp of the proximal promoter region and 122 bp of exon 1, using the base excision sequence scanning method (BESS TScan; Epicentre Technologies, Madison, WI). A total of forty genomic DNA samples from animals of different Spanish (Canaria, Malagueña, Payoya,...
