    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.

  • 蛋白标签：
    Tag type will be determined during the manufacturing process.
    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.
  • 产品提供形式：
    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.
  • 复溶：
    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.
  • 储存条件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保质期：
    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.
  • 货期：
    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.
  • 注意事项：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Q:

Hi! I'm a post-doc at the University of Parma, Italy. I managed to purify recombinant human DNASE2B from E. coli, but without any success. For the purification strategy, I chose His tag and Cobalt affinity chromatrography. May I ask you how you manage to produce this protein? Every information you could give me will be very helpful for me! I thank you in advance.

A:
Regarding the purification issue, did you only perform His tag and Cobalt affinity chromatrography purificaiton ?
Have you tried to optimize in multiple conditions, for example, to further optimize the vector, culture conditions or try some other secondary purification methods, etc.
Our article for your reference: https://www.cusabio.com/c-20275.html
Choosing an appropriate purification method is required:
For some applications, a crude extract is sufficient. However, for other uses, a high level of purity is required. To produce the protein with high purity, purifying the protein produced is necessary. Protein purification refers to a process that isolates one or more proteins from cells, tissues or whole organisms. A variety of purification strategies has been developed, such as size exclusion chromatography (SEC), separation based on charge or hydrophobicity, affinity chromatography (AC), and HPLC.
Sorry, as we haven't expressed this protein before, we are not sure if there is some special problem during the purification, some proteins are easy to purify, but others are not, which need further optimization according to our experience. Sorry, for the time being, we can't share any useful experience specific to this protein.
Probably you can try to optimize in multiple condition as we mentioend above.
