Analysis of sickle cell gene using polymerase chain reaction & restriction enzyme Bsu 361.
A 772bp DNA fragment from human beta-globin gene has been amplified by polymerase chain reaction (PCR) and subjected to restriction enzyme analysis using Bsu 361, an isoschizomer of restriction enzyme Mst II. This protocol has been designed basically to enhance the analytical facility for the detection of sickle cell mutation. A 430bp DNA fragment was found to be associated with the mutant locus, whereas 228bp and 202bp DNA fragments were generated from the normal locus. This difference of about 202bp in the resulting fragments from the mutant and normal loci has improved discriminatory power in the genotype analysis of the sickle cell mutation.
