Ku is an abundant, ubiquitously expressed nuclear protein that binds to and stabilizes the ends of DNA at telomeres or double-stranded DNA breaks. The Ku70\/Ku80 heterodimer has ATP-dependent DNA helicase activity and functions as the DNA-binding regulatory component of DNA-dependent protein kinase (DNA-PK). The assembly of the DNA-PK complex at DNA ends is required for nonhomologous end-joining (NHEJ), one mechanism involved in double-stranded DNA break repair and V(D)J recombination. DNA-PK has been shown to phosphorylate many proteins, including p53, serum response factor, c-Jun, c-Fos, c-Myc, Oct-1, Sp-1, and RNA polymerase II. The combined activities of Ku70\/Ku80 and DNA-PK implicate Ku in many cellular functions, including cell cycle regulation, DNA replication and repair, telomere maintenance, recombination, and transcriptional activation.\u003c\/p\u003e\n\n\u003cp\u003ePurification and Purity: The antibody was purified by immunogen affinity chromatography.\u003c\/p\u003e\n\n\u003cp\u003eStorage and Stability: Store at 4°C short term.

Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with the primary antibody in 3% BSA-PBS and incubated overnight at 4 °C in a hidified chamber. Cells were washed with PBST and incubated with a AF488-conjugated secondary antibody (green) in PBS at room temperature in the dark.\u003c\/p\u003e\n\n\u003cp\u003eAlternative Name: G22P2; X-ray repair cross-complementing protein 5; 86 kDa subunit of Ku antigen; ATP-dependent DNA helicase 2 subunit 2; ATP-dependent DNA helicase II 80 kDa subunit; CTC box-binding factor 85 kDa subunit; CTC85; CTCBF; DNA repair protein XRCC5; Ku80; Ku86; Lupus Ku autoantigen protein p86; Nuclear factor IV; Thyroid-lupus autoantigen; TLAA; X-ray repair complementing defective repair in Chinese hamster cells 5 (double-strand-break rejoining)\u003c\/p\u003e\n\n\u003cp\u003eImmunogen: Purified recombinant human Ku80 protein fragments expressed in E.coli\u003c\/p\u003e\n\n\u003cp\u003eConjugate: Unconjugated\u003c\/p\u003e\n\n\u003cp\u003eModification: Unmodified\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"50µl","offer_id":42989544145075,"sku":"MB66588-50","price":260.23,"currency_code":"CAD","in_stock":true},{"title":"100µl","offer_id":42989544177843,"sku":"MB66588-100","price":452.94,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/thumbnail_d1447bac803ec9be_11-14-09-19-51_99d216c0-a3b7-479a-8b40-353e83072042.jpg?v=1706095091","url":"https:\/\/afsbio.com\/products\/ku80-monoclonal-antibody-mb66588","provider":"AFSBio Inc.","version":"1.0","type":"link"}
