Conjugate Avi-tag Biotinylated
E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

Tag Info The following tags are available.
N-terminal His-tagged
Tag-Free
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
Form 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 before Lyophilization 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 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 Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
The PR65 subunit of protein phosphatase 2A serves as a scaffolding molecule to coordinate the assembly of the catalytic subunit and a variable regulatory B subunit.
Gene References into Functions
  1. MicroRNA-587 antagonizes 5-fluorouracil-induced apoptosis and confers drug resistance by regulating PPP2R1B expression in colorectal cancer. PMID: 26247730
  2. For PPP2R1B, no mutations were detected in our samples. PMID: 23588898
  3. Data show that the only gene that was expressed, although not at high levels, in all the cells carrying the 11q23.1 amplification was PPP2R1B. PMID: 21420167
  4. Data show that PR65-dominated fluctuations of PP2A have the effect of opening and closing the enzyme's substrate binding/catalysis interface, as well as altering the positions of certain catalytic residues. PMID: 20133745
  5. apoptosis mediated by Fas, TNF-alpha, and TRAIL in U937 cells is suppressed by calyculin A, an inhibitor of type-1 and type-2A protein phosphatases PMID: 14576831
  6. PPP2R1B has a role in regulating activity of specific downstream target proteins for cell cycle regulation in colorectal cancers PMID: 14767517
  7. Functional interaction between PR65, a regulatory subunit of the protein phosphatase 2A (PP2A), and CFTR was shown. PMID: 15936019
  8. These data suggest the possibility that aberrant transcripts of PPP2R1B might be associated with the development of HCC. PMID: 17324501
  9. PPP2R1B genes may not play a role in the carcinogenesis of cervical cancer. Mutations of PPP2R1B gene are not frequent in cervical cancer. PMID: 17343570
  10. PPP2R1B, together with NPAT and CUL5, is implicated in the deregulation of the cell-cycle and apoptosis regulators and in the pathogenesis of B-CLL. PMID: 17449237
  11. These observations identify PP2A Abeta as a tumor suppressor gene that transforms immortalized human cells by regulating the function of RalA. PMID: 17540176
