Descrizione generale

Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Nucleosomes consist of approximately 146 bp of DNA wrapped around a histone octamer composed of pairs of each of the four core histones (H2A, H2B, H3, and H4). The chromatin fiber is further compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures.

Specificità

A broad species cross-reactivity is expected based on conservation of sequence homology.
Recognizes Histone H2A.X phosphorylated at Ser139, Mr 15kDa.

Immunogeno

Epitope: Ser139
KLH-conjugated, synthetic peptide (CKATQA[pS]QEY) corresponding to amino acids 134-142 of human histone H2A.X. The immunizing sequence has 8 identical amino acids in yeast and mouse.

Applicazioni

Anti-phospho-Histone H2A.X (Ser139) Antibody, clone JBW301, biotin conjugate is a Mouse Monoclonal Antibody for detection of phospho-Histone H2A.X (Ser139) also known as H2AXS139P, H2AX histone & has been validated in ICC & WB.

Stoccaggio e stabilità

Stable for 1 year at -20ºC from date of receipt.
Handling Recommendations: Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variability in freezer temperatures below -20°C may cause glycerolcontaining solutions to become frozen during storage.
