1. NUCLEOTIDE CLONING METHODS 2014-12-11
Methods of cloning insert sequences into cloning vectors with high efficiency and in the correct orientation are described. In one aspect, the invention features a method of producing a plasmid comprising an insert fragment and a vector fragment in a predetermined orientation. In some embodiments, the method includes cleaving a first nucleotide sequence at a plurality of sites with a first restriction enzyme to generate a first population of nucleotide fragments, the first population of nucleotide fragments comprising insert fragments and non-insert fragments, the insert fragments comprising a non-palindromic overhang at a 5' end, at a 3' end, or at both.
Described herein are pharmaceutical compositions comprising a LMWH preparation having at least one chain having a glycol split uronic acid residue (UG) in the preparation and uses thereof.
5. METHODS FOR THE TREATMENT OF NEURODEGENERATION 2014-11-20
The invention encompasses the discovery that Fc-containing polypeptides that include branched glycans and that are sialylated on the branched glycan (e.g., on an [alpha] 1,3 and/or [alpha] 1,6 arm in the Fc region's N-linked glycosylation site), with, e.g., a NeuAc-[alpha] 2,6-Gal or NeuAc-[alpha] 2,3-Gal terminal linkage, are useful in treating neurodegeneration, e.g., in the treatment of neurodegenerative diseases such as Alzheimer's Disease. The present disclosure provides, in part, methods for treating neurodegeneration or neurodegenerative diseases by administering compositions containing such Fc-containing polypeptides as well as methods for evaluating, identifying, and/or producing (e.g., manufacturing) such polypeptides for the treatment of neurodegeneration
6. METHODS RELATED TO CELL SURFACE GLYCOSYLATION 2014-11-11
The present disclosure provides methods for assessing the glycosylation of a target glycoprotein produced by a cell through analysis of cell-surface glycans on the cell. The present disclosure therefore teaches that glycosylation of cell surface proteins can serve as a proxy for glycosylation of other proteins.
