Ribonucleoside-diphosphate reductase subunit M2 B (RRM2B), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 1-351aa. Protein Length: Full Length. Tag Info: N-terminal GST-tagged. Target Protein Sequence: MGDPERPEAA GLDQDERSSS DTNESEIKSN EEPLLRKSSR RFVIFPIQYP DIWKMYKQAQ ASFWTAEEVD LSKDLPHWNK LKADEKYFIS HILAFFAASD GIVNENLVER FSQEVQVPEA RCFYGFQILI ENVHSEMYSL LIDTYIRDPK KREFLFNAIE TMPYVKKKAD WALRWIADRK STFGERVVAF AAVEGVFFSG SFAAIFWLKK RGLMPGLTFS NELISRDEGL HCDFACLMFQ YLVNKPSEER VREIIVDAVK IEQEFLTEAL PVGLIGMNCI LMKQYIEFVA DRLLVELGFS KVFQAENPFD FMENISLEGK TNFFEKRVSE YQRFAVMAET TDNVFTLDAD F. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. 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 °C/-80 °C. 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 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Plays a pivotal role in cell survival by repairing damaged DNA in a p53/TP53-dependent manner. Supplies deoxyribonucleotides for DNA repair in cells arrested at G1 or G2. Contains an iron-tyrosyl free radical center required for catalysis. Forms an active ribonucleotide reductase (RNR) complex with RRM1 which is expressed both in resting and proliferating cells in response to DNA damage.
