Cytogenetics Laboratory

Introduction

Genetic diseases can be caused by alterations that affect entire chromosomes, chromosomal regions (chromosomal alterations), the structure or number of copies of specific chromosome regions (copy number variation, CNV), or the coding or regulatory DNA sequence of genes (genetic mutations).

Services

• Conventional cytogenetic analysis: karyotype.
• Molecular cytogenetic analysis by FISH, M-FISH and array CGH.
• Determination of alterations in the genome sequence: Sanger sequencing, quantitative PCR or fragment analysis.
• Clinical exome / exome directed panel using Next Generation Sequencing (NGS).

Equipment

• Culture room supplied with biosafety class II cabin and CO₂
• HANABI-PV Metaphase Auto-Spreader: Automated preparation of metaphases on slides maintaining constant temperature and humidity conditions.
• Metafer system: Automated system for microscopic analysis and digitization of images obtained from both optical and fluorescence microscopy.
• ThermoBrite: Programmable temperature controlled slide processing system for in-situ denaturation/hybridization procedures.
• Array CGH and NGS equipament: thermocyclers, hybridator, etc.
• SeqStudio genetic analyser system (Applied Biosystems).
• Real-time PCR Cobas 4800 (Roche).
• Sistemas de cuantificación y análisis de calidad de ácidos nucleicos: Nanodrop spectrophotometer uv-vis, Qubit fluorometer and Tape Station electrophoretic system.
