Product Specific Information
Recombinant rabbit monoclonal antibodies are produced using in vitro expression systems. Antibody DNA sequences from immunoreactive rabbits are cloned, and individual clones are screened for optimal production. Advantages include:
- Improved specificity and sensitivity
- Lot-to-lot consistency
- Animal-origin-free formulations
- Broader immunoreactivity due to the large rabbit immune repertoire
Target Information
Histone H2A.X (H2AX) is a member of the histone H2A family forming part of the nucleosome core particle. Upon DNA double-strand breaks (DSBs), phosphorylation occurs at Ser139, generating gamma-H2AX. This modification can be detected by Western blotting or immunofluorescence to assess DSB frequency.
Phosphorylation may involve kinases such as ATM, DNA-PK, and ATR. H2A.X consists of 143 amino acids and contributes to chromatin structure and DNA repair mechanisms. It maps to the 11q23.2–q23.3 region of the human chromosome.
