Tumor Necrosis Factor-Alpha (TNF-alpha) plays a major role in growth regulation, differentiation, inflammation, viral replication, tumorigenesis, and autoimmune disease. Besides inducing hemorrhagic necrosis of tumors, TNF has been found to be involved in tumorigenesis, tumor metastasis, viral...

BactoView™ Dead 760/780 is a novel near-IR fluorescent DNA dye for no-wash staining of dead bacteria. Unlike traditional dyes like PI that readily stain live gram+ cells, BactoView™ Dead dyes selectively stain dead cells in both gram+ and gram- strains. 500X in water, 100 uL.

The orexin/hypocretin peptides orexin A and orexin B (also known as hcrt-1 and hcrt-2) are 33- and 28-amino acid peptides, respectively. They are preferentially expressed in hypothalamus. The orexins have a range of physiological functions including feeding control, energy metabolism, neuroendocrine...

Single donor specimens collected during the course of infection progression.

Chemokine (C-C motif) ligand 20 (CCL20) or liver activation regulated chemokine (LARC) or Macrophage Inflammatory Protein-3 (MIP3A) is a small cytokine belonging to the CC chemokine family. It is strongly chemotactic for lymphocytes and weakly attracts neutrophils, also known as LARC (Liver and...

We developed biotin-rhodamine 110 as an alternative to biotin-4-fluorescein (90062) and fluorescein biotin (80019), both of which have been used for detection of biotin binding sites and the degree of biotinylation of proteins, and for the measurement of avidin and streptavidin in crude biological...

The IMMUNO-TEK Rat IgG ELISA* Kit is a rapid, easy to use enzyme linked immunosorbent assay (ELISA) designed for the measurement of rat IgG in rat serum, plasma, saliva, mucosa, cell culture fluid from rat cells or other biological sample.

•Perfect box for every blot •Reduce antibody usage •Hinged Lid minimizes evaporation •For halves, wholes, strips, or minisNo matter what size your Western blot is, there's a box that fits it perfectly. With boxes that are correctly matched to common blot sizes, you can fit more blots on...

Activated charcoal retains ethidium bromide, GelRed® and GelGreen® efficiently in a convenient bag for decontamination of used gel staining solutions. Each bag has a total capacity of at least 10 mg ethidium bromide.

BAPTA and its derivatives are calcium chelators that are commonly used to form calcium buffers with well-defined calcium concentrations. By injecting the chelators into cells or by incubating cells with the AM ester form of the chelators, one can control the cytosolic calcium concentration, an...

Atezolizumab is a fully humanized monoclonal antibody that is approved by the U.S. Food and Drug Administration for the trea™ent of metastatic non-small cell lung cancer (NSCLC). It binds to the protein programmed cell death-ligand 1 (PD-L1) on several tumors. Atezolizumab has ability to block...
