Human TRIT1 is a tRNA isopentenyltransferase (IPTase) homologue of Escherichia coli MiaA, Saccharomyces cerevisiae Mod5, Schizosaccharomyces pombe Tit1, and Caenorhabditis elegans GRO-1 that adds isopentenyl groups to adenosine 37 (i6A37) of substrate tRNAs. Prior studies indicate that i6A37 increases translation

Collective cell migration drives tissue remodeling during development, wound repair, and metastatic invasion. The physical mechanisms by which cells move cohesively through dense three-dimensional (3D) extracellular matrix (ECM) remain incompletely understood. Here, we show directly that migration of multicellular cohorts

Multidimensional Application of Selenium Nanoparticles

Selenium is an essential trace element. It is a necessary dietary constituent of at least 25 human selenoproteins and enzymes containing selenocysteine. Additionally, as selenium is a semiconductor and photoelectrically active, it has more advanced applications such as xerography and solar cell assembly.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
