Glial cell line-derived neurotrophic factor (GDNF) is a neurotrophic factor and a member of the tumor growth factor (TGF)-beta superfamily. The GDNF family of growth factors also includes neurturin, persephin, and artemin, which have seven conserved cysteine residues called cysteine-knot (Treanor et al.). GDNF family ligands signal through binding to specific GDNF-family receptor-α (GFRα) co-receptors and activate the RET receptor tyrosine kinase (Durbec et al.). Four different forms of GFRα co-receptors have been characterized (GFRα 1-4) out of which GDNF binds specifically to GFRα1 prior to forming a complex with RET (Airaksinen and Saarma). GDNF is known to promote survival and morphological differentiation of midbrain dopaminergic neurons in both in vivo and in vitro studies and increase their high-affinity dopamine uptake (Granholm et al.; Lin et al.). GDNF has also been shown to have restorative effects on dying dopaminergic neurons in response to degenerative toxins (Aoi et al.). GDNF, together with Human Recombinant BDNF (brain-derived neurotrophic factor; Catalog #78005), BrainPhys™ Neuronal Medium (Catalog #05790), and other supplements, can be used to differentiate human pluripotent stem cell (hPSC)-derived neural progenitor cells into neurons (Bardy et al.). This product is animal component-free.

Interleukin 34 (IL-34) is well known for its ability to induce the formation of colony-forming unit macrophages in human bone marrow cell cultures (Foucher et al.; Wei et al.). This dimeric glycoprotein is a member of the short-chain helical hematopoietic cytokine family (Baghdadi et al.; Foucher et al.), and exists in two isoforms that differ by a single glutamine (Chen et al.; Foucher et al; Wei et al.). IL-34 interacts with M-CSF to trigger tyrosine phosphorylation of the receptor and ERK1/2 pathways. (Wang et al.; Wei et al.). It is expressed in many tissues (heart, brain, lung, liver, kidney, thymus, testes, ovary, small intestine, prostate, and colon), with the highest expression in the spleen. In combination with RANKL, IL-34 induces osteoclast differentiation (Chen et al.; Foucher et al.). IL-34 expression is decreased in Alzheimer’s disease and atopic dermatitis, while high levels of IL-34 are found in many types of cancer correlated with poor prognosis, chronic heart failure or coronary artery disease, inflammatory bowel disease, influenza A infection, during acute liver transplant rejection or in non-alcoholic fatty liver disease, and with rheumatoid arthritis (Baghdadi et al.). It is therefore a possible pharmacological target for treating bone or inflammatory diseases (Chen et al.). This protein contains a His-residue tag at the carboxyl end of the polypeptide chain, and the protein was purified as a homodimer consisting of 39 kDa monomers (Lin et al.).

The VD series of vacuum drying chambers provide fast gentle drying of non flammable solvents, delivering impressive performance through their precise temperature control and gentle drying. Expansion rack technology also ensures optimal heat transfer, shelves provide flexible placement, and the interior of the chamber is easy to clean. The VDL series of safety vacuum drying chambers ensures maximum safety when drying flammable organic solvents, and have been safety tested by a state recognised test institute (GS mark). VD/VDL units can also be purchased as modular options with vacuum pump and pump chamber to form a complete system.

Interleukin-8 (IL-8) is a member of the CXC subfamily of chemokines and is produced by leukocytic cells (monocytes, T cells, neutrophils, and natural killer cells) and non-leukocytic somatic cells (endothelial cells, fibroblasts, and epithelial cells), with the most prominent source being monocytes and macrophages. Its production is induced by inflammatory stimuli, such as IL-1. IL-8, also known as CXCL8, activates neutrophils inducing chemotaxis, exocytosis, and the respiratory burst (Baggiolini and Clark-Lewis; Mukaida). IL-8 is considered one of the most potent neutrophil chemoattractants in inflammation and binds to two different chemokine receptors on leukocytes: the G protein-coupled receptors CXCR1 and CXCR2 (Hoffmann et al.; de Oliveira et al.). IL-8 has angiogenic effects on human intestinal microvascular endothelial cells in vitro that are mediated by CXCR2 (Heidemann et al.). IL-8 is reported to promote breast cancer progression by increasing cell invasion, angiogenesis, and metastasis and has been reported to be involved in regulating breast cancer stem-like cells (Singh et al.). IL-8 also has proangiogenic properties in inflammatory diseases of the conjunctiva, cornea, iris, retina, and orbit (Ghasemi et al.). It was also shown that a major T cell effector function in human newborns is IL-8 production, which has the potential to activate antimicrobial neutrophils and gamma/delta T cells (Gibbons et al.). A variety of human pathogens, such as HIV and Mycobacterium tuberculosis, have been shown to induce IL-8 production by monocytes and macrophages (Friedland et al.; Meddows-Taylor et al.).

Flt3/Flk-2 (Fms-like tyrosine kinase 3/fetal liver kinase-2) Ligand is a hematopoietic cytokine that plays an important role as a co-stimulatory factor in the proliferation, differentiation, and survival of hematopoietic stem and progenitor cells and in the development of the immune system (Hannum et al.). Flt3/Flk-2 Ligand, together with stem cell factor and thrombopoietin, is commonly used to promote expansion of primitive CD34+ hematopoietic cells in culture. In combination with myeloid cytokines such as GM-CSF, G-CSF, or M-CSF, Flt3/Flk-2 Ligand enhances the growth and numbers of clonogenic myeloid progenitor cells. In synergy with the interleukins IL-3, IL-4, IL-7, IL-11, IL-12, IL-15, and GM-CSF and TNF-α, Flt3/Flk-2 Ligand regulates the development of various lymphoid progenitor cells, including dendritic cell, B cell, T cell, and NK cell progenitors. In contrast, Flt3/Flk-2 Ligand has no significant effect on erythropoiesis or megakaryopoiesis (Drexler andamp; Quentmeier; Wodnar-Filipowicz). Flt3/Flk-2 Ligand exists as membrane-bound and soluble isoforms. Both isoforms are biologically active and signal through the class III tyrosine kinase receptor (Flt3/Flk-2, CD135; Rosnet et al.). Flt3/Flk-2 Ligand is produced by a variety of cell types, including uncommitted and committed hematopoietic cells and stromal fibroblasts, whereas expression of the Flt3/Flk-2 receptor is restricted to CD34+ hematopoietic stem and progenitor cells. Flt3/Flk-2 receptor is also expressed on leukemic cells and outside the hematopoietic system in the brain, placenta, and testis (Drexler andamp; Quentmeier; Hannum et al.).

GeneJET™ Plant Genomic DNA Purification Mini Kit is designed for rapid and efficient purification of high quality genomic DNA from a wide variety of plant species and tissue types. It utilises silica-based membrane technology in the form of a convenient spin column, eliminating the need for expensive resins, toxic phenol-chloroform extractions, or time-consuming alcohol precipitation. The standard procedure takes less than 30 minutes following cell lysis and yields purified DNA greater than 30 kb in size. DNA yields vary between different species and tissues depending on genome size, ploidy, cell number, and the age of the tissue sample. The typical yield from a standard tissue source (for example, young wheat leaves) is 30 to 32 μg from 100 mg of tissue. Isolated DNA can be used directly in PCR, qPCR, Southern blotting, and enzymatic reactions.
