The alternative pathway (AP) is one of the main routes of complement activation, and its biggest difference from the classical pathway is that it does not require the participation of C1, C4 and C2. The signal bypasses these complements and activates C3 directly, completing the start-up of downstream signaling. Serum components involved in this pathway include P, H, I, D, B and other key factors. Cell wall components such as lipopolysaccharides, peptide glycosides, and zymosan are used to activate the alternative pathway. The AP provides a rapid, antibody-independent route to complement activation. The functional analysis of this pathway can provide valuable data assistance and theoretical support for complement-related research. Here, we briefly summarize the hemolytic assay and ELISA-based assay workflow for functional analysis of AP to provide a reference for your experimental plan.
AH50 Assay Protocol
AH50 test based on hemolysis assay is recognized as the classic alternative complement pathway determination method.

ELISA-Based AP Analysis Protocol
Assays based on the ELISA format provide additional AP functional data.
