Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro309 of human POLH protein.
Background
A total of fifteen mammalian DNA polymerase enzymes catalyze the synthesis of nascent DNA during DNA replication and repair (1). DNA polymerase eta (POL η, POLH, Rad30) is one of a specialized type of DNA polymerases that function in DNA repair and translesion synthesis (TLS). POLH can accommodate and read through bulky DNA lesions such as pyrimidine dimers, which allows for continued DNA synthesis past lesions and limited stalling of replication forks (2,3). Damage inducing conditions, such as exposure to UV light or cisplatin, recruit POLH to sites of bulky DNA lesions where the polymerase interacts with PCNA (4,5). Mutations in the human POLH gene can result in a form of xeroderma pigmentosum (XPV), an autosomal recessive disorder characterized by hypersensitivity to light and susceptibility to skin cancer (6).

Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
Western Blot Buffer
IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v nonfat dry milk, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
