Abstract:
The present invention includes a highly sensitive method for detecting the presence of proteases in a sample which are present at very low levels.
Abstract:
Interleukin-10 (IL-10) conjugated via a linker to one or more polyethylene glycol (PEG) molecules at a single amino acid residue of the IL-10, and a method for preparing the same, are provided. The method produces a stable mono-pegylated IL-10, which retains IL-10 activity, where pegylation is selective for the N-terminus on one subunit of IL-10 with little or no formation of monomeric IL-10. The method also provides a substantially homogenous population of mono-PEG-IL-10.

Abstract:
Methods for purifying adenoviruses from a contaminated sample using a hydroxyapatite medium are provided. Sodium chloride concentrations present in buffers used throughout the method are at least 150 mM to prevent the adenovirus from irreversibly binding to the hydroxyapatite. Levels of contaminants and empty adenovirus capsids from samples purified by conventional purification techniques are further reduced to provide a highly pure adenovirus preparation.
Abstract:
The present invention includes a method for reducing the appearance of false positive bands in SDS-PAGE analysis of proteolytic digestion, of a sample that comprises an immunoglobulin polypeptide, at pH 8.8.
