Interferon-alpha (IFN-α) is a type I interferon, produced by virus-infected cells, and is released as a soluble factor to initiate antiviral responses (Isaacs and Lindenmann). IFN-α2 is the most potent IFN-α used in fundamental research and in most clinical applications. The best-known IFN-α2 subvariants, 2A and 2B, differ by only one or two amino acids at positions 23 and/or 34 of the mature protein (von Gabain et al.). Type I IFNs exert potent antitumor activity by increasing the cytotoxic activity of NK and T cells, as well as by inhibiting the proliferation of cancer cells (Paul et al.). Additionally, it has been shown that proinflammatory IFN-α modulates the function of B cells in patients with systemic lupus erythematosus (Chang et al.), and pegylated forms of IFN-alpha 2A and 2B have implications in the treatment of hepatitis C (Foster et al.).

Mouse Recombinant IL-2

Supplier: STEMCELL Technologies

Interleukin 2 (IL-2) is a monomeric cytokine that was originally identified as a T cell growth factor (Gaffen and Liu). It binds to a heterotrimeric receptor consisting of CD25, CD122, and CD132. Upon binding, it activates JAK3-, STAT5-, and AKT-dependent signaling pathways, which results in cellular proliferation and survival (Ma et al.). The majority of IL-2 is secreted by activated CD4+ and CD8+ T cells, although B cells and dendritic cells were found to produce IL-2 in small amounts. IL-2 downregulates immune responses to prevent autoimmunity during thymic development, influences the development of CD4+CD25+ regulatory T cells, and affects development of follicular helper T cells. IL-2 also controls inflammation by inhibiting Th17 differentiation (Banchereau et al.). Targeted deletions of the IL-2 gene in mice resulted in development of autoimmune hemolytic anemia, followed by ulcerative colitis. Similar effects were observed in mice that were deficient in IL-2 receptor α (Gaffen and Liu).

Recirculating chiller, environmentally friendly, RC 2 lite

Supplier: IKA

Compact recirculating chiller with powerful 400 W cooling capacity, designed for simple cooling tasks down to –10 °C. The RC 2 lite is the perfect peripheral device for the cooling of rotary evaporators, reflux condensers or as a cooling source for devices that dissipate heat with the help of a heat exchanger (double-walled grinding containers, cooled incubators, laboratory reactors, cooling coils). The easily accessible and easy-to-clean mesh filter along with low filling volume of just one litre enables fast cooling. Thanks to the natural refrigerant R290, the RC 2 lite is remarkably environmentally friendly.

Cooling thermostats, Alpha Series

Supplier: LAUDA

The Alpha cooling thermostats have an easy to use control console featuring three button operation and large, clear LED display, ensuring easy navigation through the menu. The thermostats are suitable for use with non flammable liquids (water, water/glycol mixtures). Units can provide both internal and external thermostating. Temperature stability of ±0,05 K gives precise heating and cooling suitable for a wide range of applications. The automatic cooling system enables cooling throughout the entire temperature range of −25 to +100 °C. All cooling thermostats contain a compressor system which can be switched on or off as required, thus conserving energy and saving wear and tear on the compressor to give a longer working life.
