{"product_id":"biolegend-504129","title":"Biolegend, 504129, Purified anti-mouse IL-4 (Maxpar® Ready) Antibody, 100μg","description":"\u003cp\u003eIL-4 is a pleiotropic cytokine produced by activated T cells, mast cells, and basophils. IL-4 is a potent lymphoid cell growth factor which stimulates the growth and activation of certain B cells and T cells. IL-4 is important for regulation of T helper subset development.\u003cbr\u003e\n100μg\u003cbr\u003e\nVerified Reactivity: Mouse\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Rat\u003cbr\u003e\nImmunogen: Partially purified native mouse IL-4\u003cbr\u003e\nFormulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and EDTA.\u003cbr\u003e\nPreparation: The antibody was purified by affinity chromatography.\u003cbr\u003e\nConcentration: 1.0 mg\/ml\u003cbr\u003e\nStorage \u0026amp; Handling: The antibody solution should be stored undiluted between 2°C and 8°C.\u003cbr\u003e\nApplication: ELISA Capture - Quality tested CyTOF® - Verified\u003cbr\u003e\nRecommended Usage: This product is suitable for use with the Maxpar® Metal Labeling Kits. For metal labeling using Maxpar® Ready antibodies, proceed directly to the step to Partially Reduce the Antibody by adding 100 µl of Maxpar® Ready antibody to 100 µl of 4 mM TCEP-R in a 50 kDa filter and continue with the protocol. Always refer to the latest version of Maxpar® User Guide when conjugating Maxpar® Ready antibodies.\u003cbr\u003e\nApplication Notes: ELISA1,2,10,13 or ELISPOT5 Capture: The purified 11B11 antibody is useful as the capture antibody in a sandwich ELISA or ELISPOT assay, when used in conjunction with the biotinylated BVD6-24G2 antibody (Cat. No. 504202) as the detecting antibody and recombinant mouse IL-4 (Cat. No. 575609) as the standard. The LEAF™ purified antibody is suggested for ELISPOT capture.Neutralization1-2,9,12: The 11B11 antibody can neutralize the bioactivity of natural or recombinant IL-4. The LEAF™ purified antibody (Endotoxin \u0026lt;0.1 EU\/µg, Azide-Free, 0.2 µm filtered) is recommended for neutralization of mouse IL-4 bioactivity in vivo and in vitro (Cat. No. 504108).Additional reported applications (for the relevant formats) include: immunoprecipitation16, immunohistochemical staining of formalin-fixed paraffin-embedded tissue sections8 and paraformaldehyde-fixed, saponin-treated frozen tissue sections6,7, and immunocytochemistry4.Note: For testing mouse IL-4 in serum, plasma or supernatant, BioLegend's ELISA Max™ Sets (Cat. No. 431101 to 431106) are specially developed and recommended.\u003cbr\u003e\nAdditional Product Notes: Maxpar® is a registered trademark of Standard BioTools Inc.\u003cbr\u003e\nApplication References(PubMed link indicates BioLegend citation): Shirai A, et al. 1994.

The regular purified format clones are formulated in solution that does not contain any EDTA. Both formulations are however without any extra carrier proteins.\u003c\/p\u003e","brand":"Biolegend","offers":[{"title":"Default Title","offer_id":46860790956201,"sku":"504129","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/biolegend-504129","provider":"Iright","version":"1.0","type":"link"}
