{"product_id":"biolegend-135521","title":"Biolegend, 135521, Purified anti-mouse CD115 (CSF-1R) (Maxpar® Ready) Antibody, 100μg","description":"\u003cp\u003eCSF-1R, also known as CD115 and M-CSFR, is a single-pass type I membrane protein and member of the platelet-derived growth factor receptor family. This c-fms (Fms proto-oncogene) gene product's natural ligands include M-CSF and IL-34. Structural studies of CD115 have described an Ig-like extracellular domain, a transmembrane domain, an intracellular juxtamembrane domain, a split tyrosine kinase domain, and a C-terminal tail receptor. Receptor activation induces homodimerization in addition to phosphorylation and ubiquitination of intracellular residues. CD115 directly influences tissue macrophage and osteoclast differentiation and proliferation. It is expressed on monocytes\/macrophages, peritoneal exudate cells, plasmacytoid and conventional dendritic cells, and osteoclasts.\u003cbr\u003e\n100μg\u003cbr\u003e\nVerified Reactivity: Mouse\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Rat\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: FC - 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: Additional reported applications (for the relevant formats) include: blocking of ligand binding1. The LEAF™ purified antibody (Endotoxin \u0026lt;0.1 EU\/µg, Azide-Free, 0.2 µm filtered) is recommended for functional assays.It has been reported that CD115 can be rapidly internalized, especially when samples are exposed to room temperature. Approximate 33% decrease in CD115 expression has been observed between 0 and 4 hours after sample collection, while overnight incubation of the cells results in complete CD115 downregulation. Pre-treatment with EDTA and low temperatures (2 to 8°C) helps in maintaining surface expression of CD1154.\u003cbr\u003e\nAdditional Product Notes: Maxpar® is a registered trademark of Standard BioTools Inc.\u003cbr\u003e\nApplication References(PubMed link indicates BioLegend citation): Sudo T, et al. 1995.

Approximate 33% decrease in CD115 expression has been observed between 0 and 4 hours after sample collection, while overnight incubation of the cells results in complete CD115 downregulation.  Pre-treatment with EDTA and low temperatures (2 - 8°C) helps in maintaining surface expression of CD115. In addition, brief fixation of the cells with Fixation Buffer (Cat. No. 420801) for 10 minutes will block CD115 internalization.\u003cbr\u003e\nQ: Can I obtain CyTOF data related to your Maxpar® Ready antibody clones?\u003cbr\u003e\nA: We do not test our antibodies by mass cytometry or on a CyTOF machine in-house. The data displayed on our website is provided by Fluidigm®. Please contact Fluidigm® directly for additional data and further details.\u003c\/p\u003e\n\n\u003cp\u003ehttp:\/\/techsupport.fluidigm.com\/\u003cbr\u003e\nQ: Can I use Maxpar® Ready format clones for flow cytometry staining?\u003cbr\u003e\nA: We have not tested the Maxpar® Ready antibodies formulated in solution containing EDTA for flow cytometry staining. While it is likely that this will work in majority of the situations, it is best to use the non-EDTA formulated version of the same clone for flow cytometry testing. The presence of EDTA in some situations might negatively affect staining.\u003cbr\u003e\nQ: I am having difficulty observing a signal after conjugating a metal tag to your Maxpar® antibody. Please help troubleshoot.\u003cbr\u003e\nA: We only supply the antibody and not test that in house. Please contact Fluidigm® directly for troubleshooting advice: http:\/\/techsupport.fluidigm.com\/\u003cbr\u003e\nQ: Is there a difference between buffer formulations related to Maxpar® Ready and purified format antibodies?\u003cbr\u003e\nA: The Maxpar® Ready format antibody clones are formulated in Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and EDTA. 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":46862536442025,"sku":"135521","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/biolegend-135521","provider":"Iright","version":"1.0","type":"link"}
