MaxDiscovery™ Human IL-2 ELISA Test Kit

Product Description
The MaxDiscovery™ Human IL-2 ELISA Test Kit is designed for quantitative determination of the concentration of human IL-2 in serum, plasma, and cell culture supernatant. Human interleukin 2 (IL-2) is a 15-18 kDa glycoprotein of 133 amino acids after cleavage of a signal peptide of 20 amino acids. It contains three cysteine residues, two of which form a disulfide bond that is required for biological activity. It is a lymphokine synthesized and secreted primarily by T helper lymphocytes that have been activated by stimulation with certain mitogens or by interaction of the T cell receptor complex with antigen/MHC complexes on the surfaces of antigen-presenting cells. The response of T helper cells to activation is induction of the expression of IL-2 and receptors for IL-2 and, subsequently, clonal expansion of antigen-specific T cells. At this level IL-2 is an autocrine factor, driving the expansion of the antigen-specific cells. IL-2 also acts as a paracrine factor, influencing the activity of other cells, both within the immune system and outside of it. B cells and natural killer (NK) cells respond, when properly activated, to IL-2. The so-called lymphocyte activated killer, or LAK cells, appear to be derived from NK cells under the influence of IL-2. Murine IL-2 is approximately 63% identical to human IL-2, but contains a unique stretch of repeated glutamine residues. There is marked species cross-reactivity as human IL-2 has been found to be active on murine cell lines. Cells known to produce IL-2 include thymocytes, ? d T cells, B cells, CD4+ and CD8+ T-cells, and neurons plus astrocytes.

Promising Class of New Cancer Drugs Cause Memory Loss in Mice
New findings from The Rockefeller University suggest that the original version of BET inhibitors causes molecular changes in mouse neurons, and can lead to memory loss in mice that receive it.
Electrical Control of Cancer Cells
Research led by scientists at The University of Texas Health Science Center at Houston (UTHealth) has revealed a new electrical mechanism that can control these switches.
Signature of Microbiomes Linked to Schizophrenia
Studying microbiomes in throat may help identify causes and treatments of brain disorder.
Inflammation Linked to Colon Cancer Metastasis
A new Arizona State University research study led by Biodesign Institute executive director Raymond DuBois has identified for the first time the details of how inflammation triggers colon cancer cells to spread to other organs, or metastasize.
Structural Discoveries Could Aid in Better Drug Design
Scientists have uncovered the structural details of how some proteins interact to turn two different signals into a single integrated output.
Determining the Age of Fingerprints
Watch the imprint of a tire track in soft mud, and it will slowly blur, the ridges of the pattern gradually flowing into the valleys. Researchers have tested the theory that a similar effect could be used to give forensic scientists a way to date fingerprints.
Genetic Overlapping in Multiple Autoimmune Diseases May Suggest Common Therapies
CHOP genomics expert leads analysis of genetic architecture, with eye on repurposing existing drugs.
Surprising Mechanism Behind Antibiotic-Resistant Bacteria Uncovered
Now, scientists at TSRI have discovered that the important human pathogen Staphylococcus aureus, develops resistance to this drug by “switching on” a previously uncharacterized set of genes.
Tissue Bank Pays Dividends for Brain Cancer Research
Checking what’s in the bank – the Brisbane Breast Bank, that is – has paid dividends for UQ cancer researchers.
Researchers Publish Landmark “Basket Study”
Researchers from Memorial Sloan Kettering Cancer Center (MSK) have announced results from the first published basket study, a new form of clinical trial design that explores responses to drugs based on the specific mutations in patients’ tumors rather than where their cancer originated.
