    Abstract: Transient gene expression is a powerful tool for plant genomics studies. Recently, the use of nanomaterials has drawn great interest. Delivery with mesoporous silica nanoparticles (MSNs) has many advantages. We used surface-functionalized MSNs to deliver and express foreign DNA in Arabidopsis thaliana root cells without the aid of particle bombardment. Gene expression was detected in the epidermis layer and in the more inner cortex and endodermis root tissues. This method is superior to the conventional gene-gun method to deliver DNA, which delivers the gene to the epidermis layer only. Less DNA is needed for the MSN method. Our system is the first use of nanoparticles to deliver DNA to plants with good efficiency and without external aids. MSNs, with multifunctionality and the capability of cargo delivery to plant cells as we demonstrated, provide a versatile system for biomolecule delivery, organelle targeting, and even agriculture, such as improved nutrient uptake.

    Abstract: The invention pertains to the generation and utility of antibodies that can bind effectively to CεmX domain on membrane-bound IgE (mIgE) expressed on the surface of human B lymphocytes. The CεmX domain of 52 amino acid residues, located between the CH4 domain and the C-terminal membrane-anchor peptide on human membrane-bound epsilon chain, had been suggested as an antigenic site for immunological targeting of B cells expressing mIgE. Previous reported monoclonal antibodies, including a20, which bind to RADWPGPP (SEQ ID NO:1) peptide at the C-terminal of CεmX, have now been found to bind poorly to mIgE on human B cells. We have discovered that only monoclonal antibodies specific for certain segments, such as GLAGGSAQSQRAPDRVL (SEQ ID NO:2) and HSGQQQGLPRAAGGSVPHPR (SEQ ID NO:3), of CεmX can bind effectively to mIgE on human B cells and hence have the utility for targeting those B cells for the treatment of diseases mediated by IgE.
