CDK4 forms a complex with D-type cyclins to phosphorylate the retinoblastoma protein (Rb), leading to the release of E2F transcription factors and progression through the cell cycle. Dysregulation of CDK4 activity is frequently observed in various cancers, making it a critical target for therapeutic intervention. Inhibitors of CDK4, often in combination with CDK6 inhibitors, are used in the treatment of hormone receptor-positive breast cancer and are under investigation for other malignancies.\u003cbr\u003e\nThe AlphaLISA SureFire Ultra Human Total CDK4 Detection Kit is a sandwich immunoassay for the quantitative detection of total CDK4 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\u003eIn the AlphaLISA SureFire Ultra assay, Donor beads are coated with streptavidin to capture one of the antibodies, which is biotinylated. Acceptor beads are coated with a proprietary CaptSure™ agent that immobilizes the other antibody, labeled with a CaptSure tag. In the presence of target protein, the two antibodies bring the Donor and Acceptor beads close together, generating signal.

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\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\n    \u003cp\u003e \u003c\/p\u003e\n\n\n\n\n            \u003cp\u003eTotal-AlphaLISA SureFire Ultra two-plate assay protocol\u003c\/p\u003e\u003cbr\u003e\n        \n\n            \u003cp\u003eThe 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.
