일반 설명

Purified mouse monoclonal antibody generated by immunizing BALB/c mice with the specified immunogen and fusing splenocytes with NS1 mouse myeloma cells. Recognizes the complexed (phosphorylated) and the ~34 kDa unphosphorylated subunit of replication protein A.
Recognizes the complexed (phosphorylated) and unphosphorylated subunits of replication protein A in HeLa and U293 cells and colon carcinoma tissue.
The replication system of a cell contains several essential components among which are replication factor A (RFA, RPA, or HeLa cell SSB), PCNA, and replication factor C (RFC) as well as several other proteins. RPA, a multi-subunit protein containing a 70 kDa, 34 kDa, and 11 kDa protein, may play a critical regulatory role in replication based on its functioning during both the initiation and elongation stages of DNA replication. The protein is highly conserved, having been identified in a range of species from yeast (Saccharomyces cerevisiae) to humans. The primary function of RPA appears to be as an auxiliary protein for both DNA polymerase α and δ. RPA undergoes a cell cycle dependent phosphorylation, which is restricted to the p34 protein. In addition to existing as part of the multi-subunit structure, p34 has also been identified as being present in a free, unphosphorylated form. Recent data shows that RPA is restricted to the nucleus and is overexpressed in transformed cells as well as in several tumor cells.

면역원

Epitope: within the p34 subunit of replication protein A
Human
replication protein A purified from U293 cells

애플리케이션

Immunoblotting (5 μg/ml)
Immunofluorescence (2.5 μg/ml)
Immunoprecipitation (1 μg/reaction)
Paraffin Sections (2.5 μg/ml, heat pre-treatment required)

물리적 형태

Lyophilized from 20 mM ammonium bicarbonate solution, 100 μg BSA.

재구성

We recommend resuspending the lyophilized antibody with sterile phosphate buffered saline (PBS), pH 7.4, or sterile 20 mM Tris-saline (20 mM Tris containing 0.15 M NaCl), pH 7.4, to yield a final concentration of 100 μg/ml; product will be more stable

기타 정보

Replication protein A (Ab-3) will react with both the complexed (phosphorylated) form of the protein as well as the free (unphosphorylated) 34 kDa subunit. Replication protein A can be used as a marker for cell division. Antibody should be titrated for op

Replication factor A (RF-A) is a multisubunit, cellular protein that functions with SV40 T antigen during the initiation stage of DNA replication at the SV40 origin. It also cooperates with other replication factors to stimulate the activity of both polymerases

Cell-free replication systems for simian virus 40 (SV40) DNA are taken to be a model for the replication of eukaryotic chromosomes, because only one viral protein is required to supplement the replication proteins provided by a human cell extract. To
