SALSA MLPA KIT P005 Human chromosomal aberration-1
[http://www.geneclinics.org/profiles/hht/details.html]
Many of the chromosomal aberrations present in human cell lines and cancer cells are numerical changes in copy number of complete chromosomes or specific chromosomal regions. This probemix contains probes for 41 different target sequences. Among these are many genes that are often deleted or amplified in various tumors. For example this kit can be used for the detection of chromosomal aberrations in small preneoplastic lesions and the determination of clonality in tumor samples. In addition, the number of chromosomal rearrangements and numerical changes in various cell lines is often very large. The SALSA MLPA kits P005, P006 and P007 can be used to prepare a fingerprint of DNA extracted from cell lines, for instance for comparison of supposedly identical cell lines from different laboratories. This SALSA MLPA kit is designed to detect deletions/duplications of one or more exons of certain chromosomal regions. Heterozygote deletions of probe recognition sequences should give a 35-50% reduced relative peak area of the amplification product of that probe. However, mutations and/or polymorphisms very close to the probe ligation site may also result in a reduced relative peak area. Therefore, apparent deletions detected by a single probe always require confirmation by other methods. We have no information on what percentage of defects in these genes is caused by deletions/duplications of complete exons. Please note that most defects in these genes are expected to be small (point) mutations, most of which will not be detected by this MLPA test.

IMPORTANT NOTICE: MLPA kits are sold by MRC-Holland for research purposes and to demonstrate the possibilities of the MLPA technique. This kit is not CE/FDA certified for use in diagnostic procedures. Salsa MLPA kits are supplied with all necessary buffers and enzymes. Purchase of the Salsa MLPA test kits includes a limited license to use these products for research purposes. The use of this MLPA kit requires a thermocycler with heated lid and sequence type electrophoresis equipment. Different fluorescent PCR primers are available. The MLPA technique has been first described in Nucleic Acid Research 30, e57 (2002)
