Let us help you with your custom method development, including:

Our custom and standard assays include:

A280

Final product concentration is easily determined by our staff without the need for custom method development.

Isotyping

Isotyping offers critical information about the characterization of your monoclonal antibody. Tests are species specific and confirm heavy and light chain class and subclass.

ELISA

Enzyme-linked immunosorbent assays (ELISAs) provide a wide range of analytical information. We offer an array of ELISAs to suit our client’s needs, from antibody concentration in cell culture to impurity levels.

SDS-PAGE Gels / IEF Gels / Western Blots

Protein electrophoresis and western blotting offers information about protein purity, charge, and specificity while utilizing standard methodology.

Size Exclusion and Affinity HPLC

Liquid chromatography provides an array of analytical options. We offer testing for protein concentration/ titer, % monomer, aggregation, degradation or we can create a custom method for your project.

Host Cell Protein (HCP)

Clearance of host cell proteins is crucial during the purification process. We offer a variety of ELISA-based assays to quantify the removal of HCPs and ensure the quality of our client’s product.

Flow Cytometry

Flow cytometry offers a wide-variety of options, including analysis of cell populations.

Enzymatic Assays

Enzymatic assays analyze differences in cellular metabolism and growth, including collagenase/gelatinase, elastase, ADP/ATP ratio and senescence.
