Abstract
The development of commercial reagents designed specifically for use with formalin-fixed paraffin-embedded (FFPE) tissue has unlocked the diagnostic potential of this prolific resource. The availability of archival FFPE tissue and tissue from current patients make it an ideal resource for molecular testing. Despite its stability and ability to preserve morphological information, FFPE provides a number of technical challenges to the study of biomolecules. In particular, the cross-linking and processing present problems in the extraction and isolation of DNA, RNA and protein and affect their use in downstream analysis. Here we will discuss some of the problems of FFPE tissue, how they can be overcome and how FFPE material can be used within clinical molecular diagnostics.

New drug therapy for eye diseases
Eyesight is one of the most critical senses, accounting for over 80% of our perceptions. Our quality of life might be significantly affected by eye disease, including glaucoma, diabetic retinopathy, dry eye, etc. Although the development of microinvasive ocular surgery reduces surgical complications and improves overall outcomes, medication therapy is ...read more
