Single-tube genotyping of MBL-2 polymorphisms using melting temperature analysis.

ABSTRACT

Recently several authors correlated MBL-2 gene polymorphisms with different pathologies and there is a growing interest for MBL-2 genotyping in a large number of individuals. We have developed a single-tube, rapid, economic, and fully automated melting temperature analysis screening method, based on ABI 7700 Sequence Detection System technology and SYBR Green I chemistry, for the detection of three polymorphisms (exon 1, codons 52, 54, 57) in the MBL-2 gene. We also developed an electronic sheet for the automatic calling of different genotypes, based on the analysis of the first derivative of ABI 7700 raw data.
