Make to order. Production time: 70-80 business days. Deliverables: 1. 200 µg antigen (used as positive control), 2. 1 ml pre-immune serum (used as negative control) , 3. Rabbit polyclonal antibody, antigen affinity purified. Quality Guarantee: 1. Antibody purity > 90% confirmed by SDS-PAGE, 2. Antibody titer > 1: 64,000 confirmed by ELISA, 3. WB positive with the immunogen protein (not applicable for synthetic peptide). Applications: ELISA, WB (positive for the recombinant immunogen protein/peptide). Buffer: Preservative: 0.03% Proclin 300, Constituents: 50% Glycerol, 0.01M PBS, pH 7.4. Protein function: DNA-dependent ATPase and 5'-3' DNA helicase required for the maintenance of both mitochondrial and nuclear genome stability. Efficiently unwinds G-quadruplex (G4) DNA structures and forked RNA-DNA hybrids. Appears to move along DNA in single nucleotide or base pair steps, powered by hydrolysis of 1 molecule of ATP. Processes at an unwinding rate of about 75 bp/s. Resolves G4 structures, preventing replication pausing and double-strand breaks (DSBs) at G4 motifs. Involved in the maintenance of telomeric DNA. Inhibits telomere elongation, de novo telomere formation and telomere addition to DSBs via catalytic inhibition of telomerase. Reduces the processivity of telomerase by displacing active telomerase from DNA ends. Releases telomerase by unwinding the short telomerase RNA/telomeric DNA hybrid that is the intermediate in the telomerase reaction. Involved in the maintenance of ribosomal (rDNA). Required for efficient fork arrest at the replication fork barrier within rDNA. Involved in the maintenance of mitochondrial (mtDNA). Required to maintain mtDNA under conditions that introduce dsDNA breaks in mtDNA, either preventing or repairing dsDNA breaks. May inhibit replication progression to allow time for repair. May have a general role in chromosomal replication by affecting Okazaki fragment maturation. May have a role in conjunction with DNA2 helicase/nuclease in 5'-flap extension during Okazaki fragment processing. [The UniProt Consortium]
