HSP90 operates through an ATP-dependent conformational cycle, assisted by co-chaperones, to facilitate protein maturation and prevent aggregation. Client proteins include kinases (AKT, BRAF), transcription factors (p53, HIF-1α), and hormone receptors (estrogen receptor, androgen receptor). HSP90 is constitutively expressed but upregulated under cellular stress conditions. In cancer, HSP90 supports the stability of mutated and overexpressed oncoproteins, making it an attractive therapeutic target. HSP90 inhibitors such as geldanamycin derivatives simultaneously disrupt multiple oncogenic pathways, leading to client protein degradation and tumor cell death, particularly in cancers dependent on HSP90 client proteins.\u003cbr\u003e\nThe AlphaLISA SureFire Ultra Human and Mouse Total HSP90 is a sandwich immunoassay for the quantitative detection of total HSP90 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.
