The p28 subunit of interleukin 27 (IL-27), also known as interleukin 30 (IL-30), is a member of the interleukin 12 (IL-12) family of cytokines. p28 is a secreted polypeptide that associates with the Epstein-Barr virus induced gene 3 (EBI3) to form the IL-27 cytokine heterodimer complex. IL-27 functions as a proinflammatory cytokine that induces immunomodulatory effects in naïve CD4+ T cells, mast cells, and monocytes. p28 can also form a complex with cytokine-like factor 1 (CLF), that is secreted by dendritic cells, to regulate natural killer (NK) and T cell functions.

Interleukin 15 (IL-15) is a widely expressed proinflammatory cytokine that is structurally and functionally related to interleukin 2 (IL-2). IL-15 signals through JAK kinases to activate STAT3, STAT5, and STAT6 transcription factors. IL-15 regulates the activation of T cells, neutrophils, and macrophages, and is a stimulatory cytokine promoting dendritic cell function. IL-15 expression is dysregulated in chronic inflammatory disorders, including rheumatoid arthritis, psoriasis, and pulmonary inflammatory diseases. Therefore, IL-15 may serve as an effective therapeutic target, due to the beneficial outcomes of IL-15 neutralisation in models of psoriasis and diabetes. Human IL-15 shows activity on mouse cells.

Cytokines for the differentation of mouse monycyte-derived dendritic cells. Dendritic cells are an important type of immune cell that function to activate T and B cells via their role as an antigen presenting cells. Monocytes isolated from bone marrow can be differentiated to immature dendritic cells (iDCs) through culturing in the presence of interleukin 4 (IL-4) and granulocyte-macrophage colony stimulating factor (GM-CSF). The characteristics of monocyte-derived iDCs are detectable after culture with IL-4/GM-CSF and include: the down regulation of CD14 surface expression, an increase in dextran uptake and an increased response to MIP-1α. Subsequent culturing with pro-inflammatory cytokines (such as TNF-α, IL-1β, and IL-6) can further differentiate the iDCs into mature dendritic cells (mDCs) that have full T cell stimulating capacity. This bundle includes 1x 100 μg of Recombinant Mouse IL-4 and 1x 100 μg of Recombinant Mouse GM-CSF.

Basic fibroblast growth factor (FGF-basic), also known as FGF-2, is expressed by endothelial cells and is a mediator of angiogenesis. FGF-basic also has cardioprotective functions during heart injury. FGF-basic is a critical component for embryonic stem cell culture systems and is necessary for maintaining cells in an undifferentiated state. Degredation of the full length FGF-basic N-terminus results in a truncated FGF-basic 147aa protein, when the protein is isolated from biological sources. The N-terminus extensions influence the localization of FGF-basic within the cell, but do not affect the biological activity of FGF-basic. Therefore, there are no detectable differences in biological activity between the full length FGF-basic 154aa and the truncated FGF-basic 147aa recombinant proteins.
