The need to identify low-level biomarkers is forcing the analytical community to deal with extremely high levels of analyte and sample complexity, which makes quantitation challenging.

As these proteins are often present at low levels in complex biological matrices, an immunoaffinity capture step is typically employed to purify the sample and increase sensitivity. This IA step is often followed by protein digestion. Current processes are often time-consuming, multistep, and prone to irreproducibility. SMART Digest IA kits solve these problems.

These IA kits deliver a process that is:

• Fast
• Simple
• Highly reproducible
• Sensitive

In SMART Digest IA Kits, the immunocapture reagents and the temperature-activated, thermally stable trypsin are co-immobilized onto a resin. Following enrichment, the enzyme is activated at elevated temperatures for accelerated digestion under protein denaturing conditions, resulting in a workflow which takes hours rather than overnight.
