{"product_id":"cst-5563s","title":"CST,  5563S, PTMScan® Phospho-Akt Substrate (RXRXXS*\/T*) Motif Monoclonal Antibody 2 Kit","description":"PTMScan for studying in the research area.\n\n\u003cb\u003eProduct Usage Information\u003c\/b\u003e\nCells are lysed in a urea-containing buffer, cellular proteins are digested by proteases, and the resulting peptides are purified by reversed-phase, solid-phase extraction. Peptides are then subjected to immunoaffinity purification using a PTMScan ® Motif antibody conjugated to protein A agarose beads. Unbound peptides are removed through washing, and the captured PTM-containing peptides are eluted with dilute acid. Reversed-phase purification is performed on microtips to desalt and separate peptides from antibody prior to concentrating the enriched peptides for LC-MS\/MS analysis. CST recommends the use of PTMScan ® IAP Buffer #9993 included in the kit.\n\u003cb\u003eStorage\u003c\/b\u003e\nAntibody beads supplied in IAP buffer containing 50% glycerol. Store at -20°C. Do not aliquot the antibody.\n\u003cb\u003eProtocol\u003c\/b\u003e\nAvailable protocols: PTMScan\n\u003cb\u003eBackground\u003c\/b\u003e\nAkt plays a central role in mediating critical cellular responses including cell growth and survival, angiogenesis, and transcriptional regulation (2-4). It is a member of an important class of kinases, referred to as Arg-directed kinases or AGC-family kinases, which includes cAMP-dependent protein kinase (PKA), cGMP-dependent protein kinase (PKG), protein kinase C, Akt, p70S6 kinase, and RSK. These kinases share a substrate specificity characterized by Arg at position -3 relative to the phosphorylated Ser or Thr (5,6). Akt, p70 S6 kinase, and RSK additionally share specificity for Arg at position -5 (recognition sequence RXRXXS\/T) (7) In a recent phosphoproteomic study (8) co-authored by scientists in the CST Site DiscoveryGroup over 300 downstream substrates for AGC family kinases recognizing the RXRXXS\/T motif were identified with PhosphoScan Technology using Phospho-Akt substrate antibodies. These CST™ antibodies are powerful tools for investigating the regulation of phosphorylation by Akt and other Arg-directed kinases, as well as for high throughput kinase drug discovery.In this assay, PTMScan (RXRXXS\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nAkt; akt1; akt2; akt3; motif","brand":"CST","offers":[{"title":"Default Title","offer_id":46800795566249,"sku":"5563S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-5563s","provider":"Iright","version":"1.0","type":"link"}
