ARID1B is particularly important for neural development, where it regulates neuronal differentiation, synaptic function, and brain morphogenesis. Haploinsufficiency of ARID1B causes Coffin-Siris syndrome, characterized by intellectual disability and developmental delay. ARID1B mutations are also found in various cancers including neuroblastoma and breast cancer, where loss of function contributes to tumor progression. The tumor suppressor function of ARID1B makes it an important target for developing epigenetic therapies.\u003cbr\u003e\nThe AlphaLISA SureFire Ultra  Human and Mouse Total ARID1B is a sandwich immunoassay for the quantitative detection of total ARID1B 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\nTotal-AlphaLISA SureFire Ultra assay principle\u003cbr\u003e\nThe Total-AlphaLISA SureFire Ultra assay measures the expression level of a protein target in a cell lysate.\u003cbr\u003e\nThe Total-AlphaLISA SureFire Ultra assay uses two antibodies which recognize two different distal epitopes 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 targeted 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 protein 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\u003eTotal-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 Total-AlphaLISA SureFire Ultra detection reagents.
