Summary: 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. They have both paracrine and autocrine function. Interleukins are also used in animal studies to investigate aspect related to clinical medicine.T cells and stem cells make IL-3. It functions as a multilineage colony-stimulating factor [1]Reference1. Justiz Vaillant AA, Qurie A. Interleukin. In:StatPearls. Treasure Island (FL): StatPearls Publishing; June 12, 2019.

Summary: A protein that combines the binding capacity of SpA and SpG is not comercially available. It can be easy created in the laboratory by combining these two immunoglobulin-binding proteins to horseradish peroxidase by the periodate method [1]. However, a mixture of SpA and SpG could have the same effect as universal reagent in immunodetection. 1. Vaillant AJ, McFarlane-Andersonv N, Wisdom B, Mohammed W, Vuma S, et al.

Summary: Keyhole limpet hemocyanin (KLH) is a cooper-containing protein comprising of subunits with MW of 400 kDa. This protein is found in the hemolymph of the sea mollusk Megathura crenulata. It has the ability to enhance the host’s immune response by interacting with monocytes, T cells and macrophages. KLH has been used primarily as a carrier for vaccines and antigens [1]. It was found that chicken immunized with KLH bound peptide raised an anti-KLH immunoresponse [2]. This can be tested by a single method such as the Ouchterlony technique.Reference1. Aarntzen EH, de Vries IJ, Göertz JH, et al. Humoral anti-KLH responses in cancer patients treated with dendritic cell-based immunotherapy are dictated by different vaccination parameters.Cancer Immunol Immunother. 2012;61(11):2003-2011. doi:10.1007/s00262-012-1263-z2.
