The most important factor when designing an IHC/ICC experiment is selection of the primary antibody. In turn, the critical feature of a primary antibody is specificity for the epitope. All steps of an IHC/ICC experiment must be optimized to visualize specific staining and minimize non-specific background signals. This includes performing initial studies to determine the appropriate incubation...

Paul Maye, Ph.D., Assistant Professor, University of Connecticut Health Center Bone marrow stromal cells have been one of the more intensively studied adult stem cell types over the past 50 years. There is great interest within regenerative medicine and wound healing for this adult stem cell type because of its complex biological properties including its ability to support a hematopoietic...

Interleukin-15 (IL-15) is a four alpha-helix bundle cytokine that is structurally and functionally related to IL-2. It is produced primarily by dendritic cells, monocytes, and epithelial cells. The heterotrimeric IL-15 receptor complex consists of a unique IL-15 R alpha subunit, IL-2/IL-15 R beta, and the common gamma-chain/IL-2 R gamma subunit. Unlike IL-2, IL-15 binds with high affinity to...

Interleukin-2 (IL-2) is an O-glycosylated four alpha-helix bundle cytokine that is primarily produced by activated T cells, dendritic cells, and B cells. The biological activity of IL-2 is mediated by binding to a cell surface receptor complex consisting of IL-2 R alpha/CD25, IL-2/IL-15 R beta, and the common gamma-chain/IL-2 R gamma subunit. IL-2 can also bind with low affinity to IL-2 R alpha...

Interleukin-21 (IL-21) is the most recently described cytokine belonging to the common cytokine receptor gamma-chain family. Like other common gamma chain family members, IL-21 is a four alpha-helix bundle type I cytokine. It signals through a receptor complex consisting of IL-21 R and common gamma-chain/IL-2 R gamma. IL-21 is produced primarily by CD4+ T cells and natural killer T (NKT) cells...
