共軛：

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?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.
產(chǎn)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.
復溶：

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.
儲存條件：

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
保質(zhì)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.
貨期：

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.
注意事項：

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

靶點詳情

功能：

Sigma factors are initiation factors that promote the attachment of RNA polymerase (RNAP) to specific initiation sites and are then released. Sigma B is not essential for sporulation; rather it is required for maximal expression of ctc and csbA which are transcribed in the early stationary phase under conditions inimical to sporulation. May play a role in the ability of the bacterium to adapt to various stresses but is not essential for its survival under these conditions. Positively regulates expression of its own operon. The second most abundant sigma factor, it associates with RNAP core under all growth phases.

3. Ectopic expression of sigma(B) and subsequent induction of spo0E cause a sigma(B)-dependent block of sporulation-specific transcription of the spo0A and spoIIE genes and produces a sporulation-deficient phenotype. PMID: 22210769
