ELISA for quantification of IL-30 in human serum. Resource Report Resource Website |
Angel Justiz-Vaillant | DOI:10.17504/protocols.io.bj3zkqp6 | University of the West Indies, [email protected] | Interleukins (IL) are a type of cytokine first thought to be expressed by leukocytes alone but have later been found to be produced by many other body cells. They play essential roles in the activation and differentiation of immune cells, as well as proliferation, maturation, migration, and adhesion. They also have pro-inflammatory and anti-inflammatory properties. The primary function of interleukins is, therefore, to modulate growth, differentiation, and activation during inflammatory and immune responses. Interleukins consist of a large group of proteins that can elicit many reactions in cells and tissues by binding to high-affinity receptors in cell surfaces. Monocytes mainly produce IL-30 in response to TLR agonists including bacterial LPS. It acts on monocytes, macrophages, dendritic cells, T and B lymphocytes, natural killer cells, mast cells, and endothelial cells. [1]Reference1. Justiz Vaillant AA, Qurie A. Interleukin.

Preparation of a protein-LA conjugated to horseradish peroxidase by the periodate method. Resource Report Resource Website |
Angel Justiz-Vaillant | DOI:10.17504/protocols.io.bjkzkkx6 | University of the West Indies, [email protected] | Protein LA, a novel hybrid protein, structurally contains 4 of the Ig Fc-binding and 4 of the Ig Fab binding regions on SpA with 4 of kappa light chain-binding sites of protein L. It has a MW of 65 kDa. Protein LA combines the binding properties of the both SpL and SpA and in some cases, give higher binding affinity than either protein alone. The binding of an Ig to SpL does not interfere with binding of another Ig molecule to the SpA domains and vice versa. Protein LA has been shown to bind effectively to immunoglobulins and their fragments from many species of animals [1]. Reference1. Justiz-Vaillant AA, Akpaka PE, McFarlane-Anderson N, Smikle MF.
