Application

Xylenes may be employed in chloramphenicol acetyltransferase (CAT) assay to evaluate the CAT gene expression.

General description

Xylenes is the mixture of isomeric ortho-, meta- and para-forms of xylene. Its dispersed emission and time of flight mass spectra has been reported. Transitions from S1 ↔ S0 states have been found to be within the range of 100cm-1 and were reported to be arising due to the internal rotation of ring methyl groups. Time-resolvedin situ FTIR spectroscopic and gas chromatographic studies have been carried out to study its diffusion coefficients, adsorption rates and isomerization efficacy over HSZM-5 surfaces.

Efficient and controllable expression of a transgene usually requires the presence of intron sequences and much efforts have been made to produce retrovirus vectors that can transduce and integrate genes with introns. However, this has proven difficult because the viral

Low-density lipoprotein receptor-related protein 1 (LRP1) is a large, endocytic cell surface receptor that is highly expressed by oligodendrocyte progenitor cells (OPCs) and LRP1 expression is rapidly downregulated as OPCs differentiate into oligodendrocytes (OLs). We report that the conditional deletion

Chimeric antigen receptor anti-CD19 (CAR19)-T cell immunotherapy-induced clinical remissions in CD19+ B cell lymphomas are often short lived. We tested whether CAR19-engineering of the CD1d-restricted invariant natural killer T (iNKT) cells would result in enhanced anti-lymphoma activity. CAR19-iNKT cells co-operatively activated
