MW: 49.4 kDa
Purity: Greater than 90% as determined by SDS-PAGE.
Endotoxin: Not test
Biological_Activity:
Form: Liquid or Lyophilized powder
Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.
Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
Relevance: Single-stranded 3'-5' DNA helicase that plays a key role in homology-driven double-strand break (DSB) repair. Involved in different DSB repair mechanisms that are guided by annealing of extensive stretches of complementary bases at break ends, such as microhomology-mediated end-joining (MMEJ), single-strand annealing (SSA) or synthesis-dependent strand annealing (SDSA). Possesses both DNA unwinding and annealing activities. Forms a complex with RAD51, stimulating HELQ DNA helicase activity and ability to unwing DNA. Efficiently unwinds substrates containing 3' overhangs or a D-loop. In contrast, interaction with the replication protein A (RPA/RP-A) complex inhibits DNA unwinding by HELQ but strongly stimulates DNA strand annealing. Triggers displacement of RPA from single-stranded DNA to facilitate annealing of complementary sequences.
