Although we offer an ever-growing range of MLPA probemixes, your application of interest may be too rare or not yet sufficiently investigated to warrant the development of a new SALSA® MLPA® probemix. Alternatively, you may have purchased a SALSA MLPA probemix and would like to add some probes of your own. In both cases, the solution is to design your own synthetic MLPA probes.

It is currently not possible to design your own digitalMLPA probes. If you are interested in a digitalMLPA probemix for a particular application, please contact us. |
About 11 probes can be included in a synthetic MLPA probemix. Designing synthetic probes consists of the following steps:
- Determining the genes or genomic region of interest.
- Obtaining genomic sequences from NCBI website.
- Determining exon boundaries and SNPs using NCBI Blast and UCSC BLAT.
- Designing your probes based on the mRNA sequence obtained.
- Ordering probes from a synthetic oligo supplier and ordering a SALSA MLPA reagent kit and/or probemix from MRC Holland.
A protocol with detailed guidelines on how to design synthetic MLPA probes and the necessary RAW program can be found in the downloads section. Unfortunately, we cannot offer additional support on probe design. Please read our synthetic probe design protocol very carefully before you start designing. To facilitate data analysis we have developed SALSA MLPA probemixes P200/P300 Reference. These probemixes contain control fragments and reference probes, and have space to include your own synthetic probes.
