DNA polymerase β (Rat) functional

Code:10-101

Backgrounds:DNA polymeraseβ is a distributive polymerase involved in base excision repair which repairs damaged DNA by excising modified bases (oxidized methylated deaminated etc.) (ref. 1).This product is highly purified full-length rat DNA polymeraseβ overproduced in E. coli with high enzymatic activity without any tag attached (ref.2).

Applications
1) For the studies on the mechanisms of base-excision repair of DNA damage
2) As a positive control of western blotting with anti-DNA polymeraseβ antibody

Proliferating Cell Nuclear Antigen (PCNA) human functional

code:10-151、10-152

PCNA (Proliferating cell nuclear antigen) is a homotrimeric protein (261 aa; 29 kDa) known to act as a co-factor for DNA polymerase  which is responsible for leading strand DNA replication. PCNA was originally identified as an antigen that is expressed in the nuclei of cells during the DNA synthesis phase of the cell cycle. Crystal structure data suggests that a PCNA homotrimer ring encircles and slides along the DNA double helix. Multiple proteins involved in DNA replication DNA repair and cell cycle control bind to PCNA rather than directly associates with DNA thus facilitating rapid processing of DNA. PCNA is a useful marker for DNA synthesis and some cancers. It is highly conserved among most amimals.
Applications confirmed:
1. Functional studies on DNA replication recombination and repair. (Ref 2 3 5 6 7 8 9 10).
2. Identification of proteins interacting with PCNA by using PCNA –conjugated resin. (Ref 1 5)
3. Ubiquitination targets (Ref 4 9 10).

Function: Ribonucleoside-diphosphate reductase subunit M2 (RRM2; 389 aa
45 kDa) also known as ribonucleotide reductase subunit R2 (RNR-R2) is a
rate-limiting subunit of an enzyme that catalyzes the formation of
deoxyribonucleotides from ribonucleotides. Deoxyribonucleotides in turn
are used in the synthesis of DNA.

Immunogen: Synthetic peptide (11 aa) in the C-terminal region of Human
and Mouse RRM2.

Application: WB IP IF IHC

Reactivity: human mouse rat hamster xenopus
