Klon: MQ1-17H12

Beschreibung: Proliferation of T lymphocytes, B cells, anti-inflammatory, hematopoiesis, tumor surveillance T cells IL-2 is a potent lymphoid cell growth factor which exerts its biological activity primarily on T cells promoting proliferation and maturation. Additionally, IL-2 has been found to stimulate growth and differentiation of B cells, NK cells, LAK cells, monocytes, and oligodendrocytes. The MQ1-17H12 antibody reacts with human interleukin-2 (IL-2). The MQ1-17H12 antibody can neutralize the bioactivity of natural or recombinant IL-2. Synonyms: Interleukin-2, T cell growth factor (TCGF), Eosinophil differentiation factor (EDF), Killer cell helper factor (KHF), Macrophage-activating factor for cytotoxicity I (MAF-C I), Thymocyte differentiation factor (TDF) Regulation: Upregulated by NFAT, downregulated by TCF-8, CIF (colostrums inhibitory factor) Structure: Cytokine, 15.4 kD (Mammalian)

Anwendungen

Applikationshinweise: ELISA or ELISPOT Capture: The purified MQ1-17H12 antibody is useful as the capture antibody in a sandwich ELISA or ELISPOT assay, when used in conjunction with the biotinylated Poly5111 antibody (ABIN160627) as the detecting antibody. The LEAF(TM) purified antibody is suggested for ELISPOT capture. Flow Cytometry: The fluorochrome-labeled MQ1-17H12 antibody is useful for intracellular immunofluorescent staining and flow cytometric analysis to identify IL-2 -producing cells within mixed cell populations. For intracellular cytokine staining protocol, please visit www.com and click on the support section. Neutralization: The LEAF(TM) purified antibody (Endotoxin <0.1 EU/µg, Azide-Free, 0.2 µm sterile-filtered) is recommended for neutralization of human IL-2 bioactivity (ABIN160081). Additional reported applications (for the relevant formats) include: immunoprecipitation, immunohistochemical staining of paraformaldehyde-fixed, saponin-treated frozen tissue sections, and immunocytochemistry. No. to) are specially developed and recommended. Each lot of this antibody is quality control tested by ELISA assay. For ELISA capture applications, a concentration range of 2-6 µg/ml is recommended. To obtain a linear standard curve, serial dilutions of IL-2 recombinant protein ranging from 2000 to 15 pg/ml are recommended for each ELISA plate. It is recommended that the reagent be titrated for optimal performance for each application.

Reinigung: The antibody was purified by affinity chromatography.

Buffer: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.

Lagerung: The antibody solution should be stored undiluted at 4° C.

Forschungsgebiet: Zytokine, Immunologie, Virologie, Inflammation, Krebs

Beschränkungen: Nur für Forschungszwecke einsetzbar
