Upon ligand binding, CSF1R undergoes dimerization and autophosphorylation, activating PI3K\/AKT, MAPK, and JAK\/STAT pathways. CSF1R is essential for tissue macrophage homeostasis, bone remodeling, and immune responses. In the tumor microenvironment, CSF1R signaling promotes tumor-associated macrophages that support cancer progression through immunosuppression and metastasis. Loss-of-function mutations in CSF1R are linked to adult-onset leukoencephalopathy and other neurodegenerative disorders, highlighting its critical role in microglial maintenance and brain health. CSF1R inhibitors are being developed as cancer immunotherapies and treatments for macrophage-driven diseases.\u003cbr\u003e\nThe AlphaLISA SureFire Ultra Mouse Phospho-CSF1R (Tyr559) is a sandwich immunoassay for the quantitative detection of phospho-CSF1R (Tyr559) in cellular lysates, using Alpha Technology.\u003cbr\u003e\nFormats:\u003c\/p\u003e\n\n\u003cp\u003eThe HV (high volume) kit contains reagents to run 100 wells in 96-well format, using a 60 μL reaction volume.\u003cbr\u003e\nThe 500-point kit contains enough reagents to run 500 wells in 384-well format, using a 20 μL reaction volume.\u003cbr\u003e\nThe 10,000-point kit contains enough reagents to run 10,000 wells in 384-well format, using a 20 μL reaction volume.\u003cbr\u003e\nThe 50,000-point kit contains enough reagents to run 50,000 wells in 384-well format, using a 20 μL reaction volume.\u003c\/p\u003e\n\n\u003cp\u003eAlphaLISA SureFire Ultra kits are compatible with:\u003c\/p\u003e\n\n\u003cp\u003eCell and tissue lysates\u003cbr\u003e\nAntibody modulators\u003cbr\u003e\nBiotherapeutic antibodies\u003c\/p\u003e\n\n\u003cp\u003eAlphaLISA SureFire Ultra kits can be used for:\u003c\/p\u003e\n\n\u003cp\u003eCellular kinase assays\u003cbr\u003e\nReceptor activation studies\u003cbr\u003e\nHigh-throughput screening for preclinical studies\u003cbr\u003e\nHow it works\u003cbr\u003e\nPhospho-AlphaLISA SureFire Ultra assay principle\u003cbr\u003e\nThe Phospho-AlphaLISA SureFire Ultra assay measures a protein target when phosphorylated at a specific residue.\u003cbr\u003e\nThe assay uses two antibodies which recognize the phospho epitope and a distal epitope on the targeted protein. AlphaLISA assays require two bead types: Acceptor and Donor beads. Acceptor beads are coated with a proprietary CaptSure™ agent to specifically immobilize the assay specific antibody, labeled with a CaptSure tag. Donor beads are coated with streptavidin to capture one of the detection antibodies, which is biotinylated. In the presence of phosphorylated protein, the two antibodies bring the Donor and Acceptor beads in close proximity whereby the singlet oxygen transfers energy to excite the Acceptor bead, allowing the generation of a luminescent Alpha signal. The amount of light emission is directly proportional to the quantity of phosphoprotein present in the sample.\u003c\/p\u003e\n\n\n  \u003cbr\u003e\n        \n\n\n\t\u003cbr\u003e\n  \u003cbr\u003e\n        \u003cbr\u003e\n  \n\n      \u003cbr\u003e\n  \u003cbr\u003e\n  \u003cbr\u003e\n    \u003cbr\u003e\n      \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n      \u003cbr\u003e\n    \n\n    \u003cbr\u003e\n      \n\n      \u003cbr\u003e\n        \n\n      \u003cbr\u003e\n    \n\n  \n\n\n\n\n\u003cp\u003e \u003c\/p\u003e\n\n\n\u003cp\u003ePhospho-AlphaLISA SureFire Ultra two-plate assay protocol\u003cbr\u003e\nThe two-plate protocol involves culturing and treating the cells in a 96-well plate before lysis, then transferring lysates into a 384-well OptiPlate™ plate before the addition of Phospho-AlphaLISA SureFire Ultra detection reagents.
