Anti-Casein Kinase II Subunit Beta CSNK2B Antibody – Research Use Only

Anti-Casein Kinase II Subunit Beta (CSNK2B) Antibody is a high-quality polyclonal antibody supplied as a 100 µL liquid (Catalog #B2023555). It specifically recognizes the beta subunit of casein kinase II (CK2β, ~25 kDa), a regulatory component of the CK2 heterotetrameric serine/threonine kinase complex involved in cell cycle control, apoptosis regulation, DNA repair, and multiple signaling pathways.

Scientific Overview

Casein Kinase II (CK2) is a ubiquitous serine/threonine protein kinase composed of two catalytic α (or α′) subunits and two regulatory β subunits. The β subunit (CSNK2B) modulates substrate specificity, stability, and localization of the holoenzyme. CK2β participates in the regulation of cell cycle progression, apoptosis, DNA damage response, and transcription. Dysregulation of CK2 activity is frequently observed in cancer, making CSNK2B a relevant target for biomarker and mechanistic studies.

This Anti-Casein Kinase II Subunit Beta CSNK2B Antibody is suitable for:

• Western blot detection of endogenous and recombinant CSNK2B (~25 kDa)
• Immunohistochemistry and immunofluorescence localization of CK2β in tissues and cells
• Immunoprecipitation of CK2 complexes
• Studies of CK2β function in cell signaling, cell cycle, and apoptosis
• Research on CK2 in cancer biology and therapeutic targeting

Usage & Handling Guidance

Store at -20 °C. Avoid repeated freeze–thaw cycles by preparing single-use aliquots. For Western blotting, typical dilutions range from 1:500 to 1:2000. For IHC/IF, optimize starting from 1:100–1:500. Centrifuge briefly before use if necessary.

• Recommended applications: Western blot, IHC, IF, and IP
• Working dilution: Optimize empirically (commonly 1:500–1:2000 for WB; 1:100–1:500 for IHC/IF)
• Stability: Stable when stored frozen; aliquot to prevent repeated freeze–thaw
• Handling: Use in a clean environment; validate specificity with appropriate controls (e.g., knockdown or blocking peptide)
