Porcine Cluster Of Differentiation 40 Ligand (CD40L) ELISA Kit

This Assay Genie ELISA kit quantifies porcine cluster of differentiation 40 ligand (CD40L) in a microplate-based colorimetric workflow. CD40L is a TNF-family co-stimulatory molecule expressed on activated T-helper cells; engagement of CD40 on B lymphocytes and antigen-presenting cells drives B-cell activation, immunoglobulin class switching, and downstream cytokine release, making CD40L a meaningful biomarker in immune-response studies.

The assay follows an antibody-pair binding format: capture-antibody-coated wells receive standards and diluted unknowns, then a labeled detection antibody, and finally a chromogenic substrate whose absorbance scales with CD40L content in the specimen. Compatible specimen types span porcine blood-derived samples (serum preparations and plasma fractions) and tissue homogenate, supporting applications such as swine infectious-disease modeling, transplantation immunology work, and vaccination response profiling.

Kit components include the microplate, lyophilized standards, detection antibody, chromogenic substrate solution, wash buffer, and diluent. Reconstituted reagents should be aliquoted and stored frozen at sub-zero temperatures; the kit is supplied for research use only and not for diagnostic or clinical use. A full package supports ninety-six determinations.
