Use of confocal microscope has provided many recent developments in the study of functional aspects, especially localization and distribution of proteins, DNA and RNA within the cells. In the present investigation, we have applied for the first time, antisense molecular beacon based Fluorescence Resonance Energy Transfer (FRET) and Flow Cytometric Energy Transfer (FCET) techniques to demonstrate binding and colocalization of fibrillarin protein with small nuclear RNA (snRNA) to form ribonucleoprotein particle (RNPP) complex in Giardia lamblia. It has been observed by FRET and FCET that energy transfer occurs from fluorescence tagged fibrillarin to snRNA antisense molecular beacon confirming the clear physical interaction between them during RNPP complex formation. This is the first demonstration of in situ detection of RNA-protein complex formation by antisense molecular beacon based FRET and FCET in Giardia lamblia.
