ABSTRACT
Cancer is a disease that begins in the cells of the body which is characterized by uncontrolled, uncoordinated and undesirable cell division. If a cell accumulates critical mutations in five or six of the protooncogenes, tumour suppressor genes and DNA repair genes are likely to result in a fully malignant cell, capable of forming a tumour. In this work we described the isolation and amplification of the BRCA1 gene. Primers were designed and synthesised later used to amplify the BRCA1 gene. The total new workflow includes all steps from purified DNA to data analysis, and includes PCR for all amplicons covering the gene, PCR cleanup, cycle sequencing, electrophoresis, and data analysis. To simplify workflows and decrease the time-to-result, we focused on the method “one sample, one assay” approach. The success of this workflow was the 24-well plate design, which contained prespotted PCR primers covering the gene and also included multiplex nontemplate controls. The workflow was developed using a Genetic Analyzer and bands were observed.
