Be Confident In Your Process and Product

Does your process consistently produce a high yield of a high-quality product? Even if your answer is yes – it could be better! With our selection of flexible and fully-integrated solutions, you can easily check for antigen specificity, critical epitopes of mAbs, binding to Fc receptors, enzymatic activity and more. Getting reliable results, top-notch data quality and access to expert support means you can rest assured that your therapeutic product is as expected.

Protein Bioprocessing: we offer a selection of flexible and fully-integrated solutions for your workflow.

Are You On Target For Antibody Specificity?

When you need to confirm that your antibody can recognize its target and are fed up with variable data, our Immunoassay Services can make it easy for you.

Precision, recovery, linearity and sensitivity can be yours without lifting a finger – by combining world class expertise with extensively tested and qualified materials, we deliver tailored and optimized Quantikine ELISA kits that work for you.

Don’t just take our word for it – our Quantkine ELISA kits are the most referenced ELISA kits on the market!

Multiplex With Luminex®

Building a comprehensive picture of immune response doesn’t have to be complicated – and it doesn’t have to deplete your resources. Multiplexing with Luminex from Bio-Techne brand R&D Systems means you can enjoy the data quality of ELISA and qPCR but with greater efficiency and throughput – saving you time, money and sample.

The Simple Western Instrument Family

Simple Screening with Simple Western

Characterize your product directly in complex samples using only 3 µL of sample. No sample cleanup required. Combining CE-SDS/cIEF with antibody-based immunodetection using Simple Western™ is more sensitive than traditional CE-SDS/cIEF with native fluorescence detection. Plus, Simple Western provides accurate, quantitative results you won’t get with ELISA or Western blot, and results are ready in just 3 hours. 

Protein A Impurity

With so many impurities to measure, make protein A simple with a 1-step sample pre-treatment assay.

The Next Generation ELISA...

ELISA is the gold standard for measuring protein impurities, so why settle for ELISA experiments that keep giving you less than optimal results? With automation, you can say goodbye to inconsistent manual results – and save time in the process!

Take your ELISA’s to the next level with Ella. In just 90 minutes, she’ll deliver you highly reproducible, validated assay data with no manual steps. Low impurity concentration? Ella’s got you covered with sub-picogram sensitivity and 4+ logs of dynamic range.

Binding Assays

To Bind or Not To Bind?

If you’re asking whether your antibody shows the right binding - or lack thereof - we’ve got the answer! Confirm that the constant region of your therapeutic monoclonal antibody shows the right binding to specific Fc receptors with:

  • Fc Receptor Proteins
  • Fc Receptor Antibodies
  • Antibody-Protein Pairs
