The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/2000 - 1/10000. Detects a band of approximately 33 kDa (predicted molecular weight: 23 kDa).
Use at 2-5 µg/mg of lysate.
1/1000 - 1/5000. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
Antigen retrieval with Tris-EDTA pH9.0 is recommended for human tissues. Antigen retrieval with citrate buffer pH6.0 is recommended for mouse tissues.
Single-stranded DNA (ssDNA)-binding proteins, such as OBFC2B, are ubiquitous and essential for a variety of DNA metabolic processes, including replication, recombination, and detection and repair of damage.
OBFC2B plays an important role in DNA damage response. It influences diverse endpoints in the cellular DNA damage response, including cell-cycle checkpoint activation, recombinational repair and maintenance of genomic stability. It associates with DNA lesions, and enables the efficient activation of ATM and consequent phosphorylation of downstream proteins.
Nuclear. Localizes to nuclear foci following DNA damage.
