Cytosolic Delivery of Anticancer Drug Using Endosomolytic Peptide Bearing Nanoparticles Against Solid Tumor
Satish Shilpi, Sanjay K. Jain

The objective of the present project is to develop transferrin coupled biodegradable nanoparticles (NPs) with high encapsulation efficiency (Doxorubicin). GALA (Glutamic acid-alanine-leucine alanine) a pH sensitive fusogenic endosomolytic peptide is added to the formulation to enhance the endosomal lysis that will further potentiate the delivery of anticancer drug inside tumor cell as well as prevent loss of drug via endosomes.

Fast Liquid Differential Scanning Calorimetry (FLDSC)
R. Splinter, A.W. van Herwaarden, A. Pfreundt, W.E. Svendsen, D. Istrate, W. van Eijk

Lysozyme experiments show that protein unfolding can be recorded at scan rates of up to 1000 °C/s, and for lysozyme concentrations of 1 % and probably even down to 0.1%.

Monitoring Protein Synthesis in Living Cells With Fluorescent Labeled tRNA FRET Pairs
Zeev Smilansky, Sima Barhoom, Ian Farrel, Dvir Dahary, Andrew Leask, Peter Vanderklish, Marcelo Ehrlich, Barry S. Cooperman and Orna Elroy-Stein

We transfect cells with tRNAs labeled as FRET donors and acceptors. A FRET signal is generated only when a donor labeled tRNA and an acceptor-labeled tRNA come in close contact (< 7 nM), as they do on the ribosome during the elongation cycle. The intensity of the FRET signal correlates with the number of ribosomes engaged in protein synthesis, providing a real-time, live-cell assay for measuring rates of protein synthesis.
