SeqNext is a very powerful and user-friendly software module for mapping, basecalling and variant detection with next-generation sequencing data from all main sequencing platforms. SeqNext can handle all kinds of pre-capturing/amplification methods and kits. Visualisation of the variants, data exchange and reporting are simple and intuitive. It detects SNPs, insertions and deletions of any length as well as CNV. It offers access to SNP-databases like dbSNP, 1000 Genomes, COSMIC, ClinVar and CLINVITAE.

SeqPatient is a sophisticated software module conceived for the analysis of Sanger sequencing data. The software is structured to support the daily work of molecular biology and diagnostic laboratories. Analysis of genomic DNA and cDNA is possible. A statistical function and internal mutation database supports the decision-making process. Get the maximum output from your data through the robust, secure and professional analysis workflow of this powerful tool.

SeqHLA is a powerful tool for HLA labs utilizing conventionial Sanger sequencing technology to perform HLA typing. Statistical functions, automatic use of all previously made analyses as controls for your actual samples, clear data and result visualisation, availability of HLA databases, different resolution types and many other features make this module a "must have" for HLA laboratories.

SeqNext-HLA is conceived for the easy analysis of next-generation sequencing data obtained from HLA-samples. It is basically an adaptation of the standard SeqNext module for HLA typing applications.

It is independend of the used sequencing platform and assay. Exon and intron data are analysed, null alleles as well as new alleles are called.

Haplotype(s), allele ambiguities and NMDP codes are listed. Regular updates to the latest HLA database version guarantee up-to-date results.

MLPA® is also the name of our software module designed for MLPA® data analysis. Peak assignment is automated and control settings can be easily configured. You can view both raw data and statistical analysis for each sample. We also offer mix-descriptions as downloads from our website. MLPA® data analysis has never been this easy.

varSEAK is a global database for genetic variants, including ACMG-compliant classifications. In addition to that, varSEAK offers efficient and customizable filter stategies, bundled information from all relevant public databases, direct contact options for professional exchange between varSEAK users, features for quality control and many more. varSEAK is directly connected to SEQUENCE Pilot and therefore can seamlessly be integrated into your daily workflow, from filtering and classifying of variants up to report creation.
