Your project is important.

Get the unfair advantage with ZipChip.

Charge variant analysis that gives you more.

Charge variant separations like icIEF and CEX are great, but without mass spec analysis how do you really know what you’re seeing? ZipChip performs charge variant analysis of biotherapeutics and gives you more than just a separation. Here’s the big difference: It adds another layer of information with the power of mass spec characterization. More data with every run means that every variant is an identified variant.

Suggested Resources

Really know your product.

The ZipChip’s charge variant assay alone gives you more information than other techniques. The same goes for other characterization assays. Whether you’re running intact charge variant analysis, reduced analysis, or peptide mapping, ZipChip works at every level.

Suggested Resources

Not an antibody? No problem.

ZipChip separates subtly different protein variants to characterize complex molecules like fusion proteins, bispecifics, glycoproteins, or even a mix of proteins in one sample. Chips and assay kits can handle complex sample matrices so detergents aren’t a problem either.

Suggested Resources

A big advantage for small molecules.

ZipChip lets you take on anything from bioreactor media to metabolites in biofluids like plasma or urine. Sample prep is simple. There’s no labeling or derivatization, and no dry down when your sample matrix has organics. Add internal standards for full quantitation on a variety of analytes.

Suggested Resources

No chance for mistaken identity.

What if your target analytes have the same mass? Your mass spec may not be able to tell the difference, but ZipChip can. It can separate isomers of small molecules and peptides based on subtle structural differences. That means target analytes are unequivocally identified every time.

Cool new stuff.

Experience the joy of analyzing monoclonal antibodies in their native state!

Detergents slowing you down? ZipChip loves detergents. See for yourself!
