Protein Length
Full Length of Mature Protein
Tag Info
N-terminal 6xHis-SUMO-tagged
Form
Liquid or Lyophilized powder
Note: We will preferentially ship the format that
we have in stock, however, if you have any special requirement for the format, please remark your
requirement when placing the order, we will prepare according to your demand.
Buffer
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the
glycerol content, please remark when you place the order.
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°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw
cycles.
Shelf Life
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°C/-80°C. The shelf life of lyophilized
form is 12 months at -20°C/-80°C.
Lead Time
3-7 business days
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Description
Recombinant Human RPA1 expression in E.coli requires the insertion of the target DNA fragment into an E.coli expression vector, routinely a plasmid vector, and the transferral of this vector into E.coli cells. The cells are then cultured and induced to express this RPA1 protein. The cells are harvested by centrifugation, samples prepared and proteins detected by polyacrylamide gel electrophoresis and subsequent staining of the gel with Coomassie Brilliant Blue or silver stain or by immunoblotting. The RPA1 protein expression in E.coli is highly scalable and can be adjusted from the bacterial colony to conical flasks for liquid cultures, to fermentation reaction chambers.
RPA1 is a protein coding gene that encodes Replication protein A 70 kDa DNA-binding subunit. According to some studies, RPA1 may have the following features.
The function of Rpa1 in DNA metabolism is critical for maintaining chromosomal stability and suppressing tumors. Binding of RPA1 to NRF2 switches ARE-dependent transcriptional activation to ARE-NRE-dependent repression. The acetylation state of RPA1 plays a critical role in repairing DNA damage through NER. RPA1 has multiple roles in the body, playing a role in DNA replication, repair and recombination. The physical interaction between Rfc4 and Rpa1N is required for both effects. K163 acetylation of RPA1 plays a key role in repairing UV-induced DNA damage.
