In situ hybridization: a course on FISH and ChIp
In situ hybridization – a course on FISH and ChIp In situ hybridization, now largely with fluorescent detection so ‘fluorescent in situ hybridization’ or FISH, is a key method for localizing DNA sequences along chromosomes and occassionally within interphase nuclei. RNA in situ hybridization (not discussed here) is used for locating gene transcripts within nuclei….

Nouf Alsayied: PhD student with Saffron Crocus at the University of Leicester and faculty member Umm Al-Qura University, Kingdom of Saudi Arabia
My research focuses on understanding the origin and diversity of the genus Crocus (Iridaceae), with particular emphasis on a triploid sterile plant, Crocus sativus (2n=3x=24) that yields Saffron, one of the most expensive spices on earth. The saffron is the stigmas of the flowers, and nearly 200,000 must be collected to give 1kg of spice,…
