What are recombinant multiclonals?
Recombinant multiclonals are a mixture of recombinant antibodies co-expressed from a library of heavy and light chains. They offer several advantages including:
- - The sensitivity of polyclonal antibodies by recognising multiple epitopes
- - High batch-to-batch consistency and reproducibility
- - Improved sensitivity and specificity
- - Long-term security of supply
- - Animal-free batch production

Biological function summary
Calprotectin serves as an important player in the immune response. This complex possesses antimicrobial properties and contributes to the body's defense by modulating inflammation. It binds to zinc and manganese to deprive pathogens of essential nutrients an action called nutrient bioavailability restriction. In immune cells calprotectin's presence signals the activation and recruitment of further immune components.
Pathways
S100A8 and S100A9 influence the NF-kB signaling pathway which governs immune responses and inflammation. Their function affects other pathways such as MAPK by mediating pro-inflammatory cytokines' production and release. These proteins often engage with Toll-like receptors impacting the innate immune system and contributing to the body's defensive mechanisms against pathogens.
