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.

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
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
(From Uniprot)
Serine protease inhibitor selective for kallikreins. Efficiently inhibits KLK4, KLK5, KLK6, KLK7, KLK12, KLK13 and KLK14. Doesn't inhibit KLK8.
Gene References into Functions
  1. Study showed that the expression of SPINK6 is specifically suppressed in liver tumor tissues. The suppression could be even detected in the early stage tumors. As SPINK6 is a secretory protein, the extracellular protein level may be decreased because of tumor development. These results support that SPINK6 is an important tumor suppressor in liver. PMID: 27999203
  2. our results identified a novel EGFR-activating mechanism in which SPINK6 has a critical role in promoting nasopharyngeal carcinoma metastasis PMID: 27671677
  3. a significant fraction of SPINK6-sensitive proteases in healthy saliva and confirmed the ability of gingipains to inactivate SPINK6 under ex vivo conditions PMID: 27354280
  4. KLKs. Thereby, beside the conserved binding mode, we identified an alternate binding mode which has so far not been observed for SPINK inhibitors. PMID: 26828269
  5. Our study indicates that Spink6 is a potent inhibitor of kallikrein related peptidases and involved in skin barrier function. PMID: 24352040
  6. Cross-linked SPINK6 might protect specific substrates such as fibronectin from kallikrein-related peptidases cleavage and contribute to the regulation of proteases in the epidermis. PMID: 23303447
  7. Serine protease of Kazal-type (SPINK6) expressed in normal human skin is a potent natural inhibitor of Kallikrein-related peptidases, KLK12 and KLK13. PMID: 21439340
  8. Data suggest that SPINK6 plays a role in modulating the activity of kallikreins in human skin. PMID: 20667819
