Oligoclonal™ Antibodies – A Revolutionary Approach

Absea’s Oligoclonal Antibodies are a novel class of antibodies that combine the benefits of both monoclonal and polyclonal antibodies. These products consist of two or more fully characterized monoclonal antibodies, mixed in precise proportions, to target different epitopes of the same antigen.

Advantages of Oligoclonal Antibodies

• High Reproducibility – Batch-to-batch stability and a defined and controllable formulation guarantees consistent performance across experiments.
• High Specificity – Each monoclonal antibody in the oligoclonal mixture targets a specific epitope of the antigen, thereby minimizing the risk of nonspecific binding.
• High Sensitivity – Oligoclonal Antibodies bind to multiple epitopes simultaneously, increasing sensitivity in detection and enabling analysis of low-abundance targets.
• Low Background – Compared to polyclonal antibodies, Oligoclonal Antibodies have reduced background noise, resulting in a higher signal-to-noise ratio that is ideal for various detection applications.

Cross-Linking Mass Spectrometry (XL-MS) – Unlocking Protein Interactions

Absea’s XL-MS service is a powerful tool for studying protein interactions and structural relationships under native conditions. Their advanced workflows allow researchers to analyze complex biological samples without requiring protein engineering or cell lysis, preserving the integrity of protein interactions.

Applications of XL-MS

• Mapping protein interactomes in diverse physiological and pathological conditions
• Identifying binding partners of clinically relevant proteins
• Discovering protein interactions for biomarker and drug target research

Supporting Advanced Proteomics Research

In addition to its core product offerings, Absea provides specialized mass spectrometry services, such as affinity purification-mass spectrometry (AP-MS), to characterize protein interactors. These comprehensive solutions enable researchers to gain critical insights into protein networks, advancing discoveries in proteomics, diagnostics, and drug development.
