About this person


Molecular biology:

  • Experience on  DNA and RNA extraction from different tissues, cDNA synthesis, cloning, probe making methodologies (cRNA) as well as PCR.   
  • Experience on gene quantification using Real Time qPCR and genes distribution using In Situ Hybridisation (ISH) methodology, DAB and fluorescence Immunohistochemistry. 
  • Laser micro dissection: advanced tool to isolate and capture of specific cells for gene expression.
  • DNA analysis by micro-satellite mapping techniques.                                      
  • Measurement of  circulating hormone level using  ELISAs.

Histology: Experience on  preparation of histological samples (sampling, fixation, embedding, cryosectioning)

Cellular Biology: organ culture of fish gills, total RNA extraction from cells

Instruments: FAST- prep FP 120, BIO 101 Thermo Savant, Cryostat Leica CM 3050S Agilent 2100 Bio analyzer, InsituPro,  nanodrop 1000ND Spectrophotometer.
