Abstract: A method of generating an internally fixed lipid vesicle, comprising: providing a precursor lipid vesicle that contains an aqueous interior enclosed by a lipid membrane, wherein the lipid membrane of the precursor lipid vesicle is non-permeable to a crosslinker; permeabilizing the lipid membrane transiently to generate a permeable vesicle; contacting the permeable vesicle with an inactive activatable crosslinker, whereby the inactive activatable crosslinker enters the permeable vesicle; allowing the permeable vesicle to return to a non-permeable vesicle; removing any extravesicular crosslinker; and activating the inactive activatable crosslinker to allow crosslinking to occur inside the non-permeable vesicle, whereby an internally fixed lipid vesicle is generated.

Abstract: Aluminum coated glass slides provide a novel glycan array platform. Specifically, aluminum coated glass slides increase sensitivity of fluorescent based assay methods. Additionally, aluminum coated glass slides allows for mass spectroscopic analysis of carbohydrates and provide a platform for examining activity of cellulases. The unique properties of ACG slides include: 1) the metal oxide layer on the surface can be activated for grafting organic compounds such as modified oligosaccharides; 2) the surface remains electrically conductive, and the grafted oligosaccharides can be simultaneously characterized by mass spectrometry and carbohydrate-binding assay; and 3) the slides are more sensitive than transparent glass slides in binding analysis.

Abstract: The present disclosure relates to glycoproteins, particularly monoclonal antibodies, comprising a glycoengineered Fc region, wherein said Fc region comprises an optimized N-glycan having the structure of Sia2(?2-6)Gal2GlcNAc2Man3GlcNAc2. The glycoengineered Fc region binds Fc?RIIA or Fc?RIIIA with a greater affinity, relative to comparable monoclonal antibodies comprising the wild-type Fc region. The monoclonal antibodies of the invention are particularly useful in preventing, treating, or ameliorating one or more symptoms associated with a disease, disorder, or infection where an enhanced efficacy of effector cell function (e.g., ADCC) mediated by Fc?R is desired, e.g., cancer, autoimmune, infectious disease, and in enhancing the therapeutic efficacy of therapeutic antibodies the effect of which is mediated by ADCC.
Abstract: The present invention relates to a method for enhancing root growth of a plant by introducing a polynucleotide encoding late embryogenesis abundant protein, group 3 (LEA3) into the plant.
