GE Healthcare launched last week its DeCyder 2D 7.1 SPN software package for the characterization and quantitation of host cell proteins – a quality assurance parameter used in biopharmaceutical work.
The software provides an antibody-independent method of directly comparing target protein/HCP profiles between samples taken at various steps of biopharmaceutical processing, the company said in a statement.
OriGene Technologies announced last week at the 2010 American Society for Mass Spectrometry conference the production of over 5,000 heavy isotope labeled human proteins to be used as internal standards for SRM and MRM mass spectrometry.
The newly released protein standards will allow for more accurate targeted protein quantitation compared to heavy labeled AQUA peptides, the company said in a statement.
AnaSpec introduced this week its new Rhodamine 110 Labeled GO Peptides designed for the study of proteases like cysteine aspartate-specific proteases and serine proteases.
The Rhodamine 110 Labeled GO Peptides are generally cell permeable, making them useful in intact cells for applications like flow cytometry. Because Rh110 emits in the green range, autofluorescence interference from cellular components is minimal, the company said in a statement.
