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
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.
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.
Troubleshooting and FAQs
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
Glandular kallikreins cleave Met-Lys and Arg-Ser bonds in kininogen to release Lys-bradykinin.
Gene References into Functions
  1. glycosylation changes the enzymatic activity of KLK2 in a drastically substrate-dependent manner. PMID: 26582203
  2. The results indicated that W-hK2 had a defect in cellular trafficking due to its misfolding and that it activated the unfolded protein response, suggesting a mechanism to explain the association of the T allele with higher prostate cancer risk. PMID: 25847286
  3. miR-378 was predicted to target both KLK2 and KLK4 and downregulated levels detected in prostate cancer patients. PMID: 25153390
  4. The differential regulation of alternative transcripts (using KLK2, KLK3 and KLK4 as models) by androgens and anti-androgens as an indicator of prostate cancers, was investigated. PMID: 25153393
  5. Structure-function analyses of KLK2 establish the 99-loop as master regulator of its activity. PMID: 25326387
  6. Predictions based on levels of four kallikrein markers, including KLK2, in blood distinguish between pathologically insignificant and aggressive disease after radical prostatectomy with good accuracy. PMID: 23683475
  7. Alteration of cellular junctions in benign prostatic hyperplasia could contribute to the presence of luminal epithelial secreted proteins prostate specific antigen (PSA)2 and and KLK2 in the stromal compartment. PMID: 24711254
  8. we present the first evidence that KLK2 can also function as an androgen receptor modulator that may modulate cell growth after the development of castration-resistant prostate cancer PMID: 24122203
  9. Associations observed in young, healthy men between the seminal plasma and serum concentrations of hK2 and PSA and several genetic variants in KLK2 and KLK3 could be useful to refine models of PSA cutoff values in prostate cancer testing. PMID: 24270797
  10. Genetic variants at ATF7IP and KLK2 contribute to the variance of %fPSA. PMID: 23359319
  11. Two SNPs, in beta-microseminoprotein at and in kallikrein-related peptidase 2 at, are associated with PCA3 score at genome-wide significance level PMID: 23555189
  12. TK promotes vessel growth by increasing the number of EPCs and enhancing their functional properties through the kinin B(2) receptor-Akt signaling pathway. PMID: 22435954
  13. An exploratory study of a KLK2 polymorphism as a prognostic marker in prostate cancer was found to be less likely associated with low Gleason score morphology. PMID: 21178268
  14. we identifiedand genotyped novel single-nucleotide polymorphisms in cancer cases and controls which verified prior associations in KLK2 and in MSMB (but not in KLK3) with prostate cancer PMID: 20424135
  15. Data show six non-synonymous amino acid or frame shift changes in the KLK3 gene and three changes in each of the neighboring genes, KLK15 and KLK2. PMID: 19823874
  16. The identification of unusual mRNA splice variants of the KLK2 and KLK3 genes that result from inclusion of intronic sequences adjacent to the first exon. PMID: 11834722

  18. kallikrein expression in nipple aspirate fluid- ethnic variation PMID: 12209605
  19. Measurements of free prostate specific antigen and hK2 improve on our ability to counsel patients prior to treatment as to their risk of biochemical recurrence PMID: 16152616
  20. An additional serum marker for the detection of prostatic cancer. PMID: 16388506
  21. a role for the KLK2 gene in prostate cancer susceptibility PMID: 17085659
  22. results imply that prostate cancer risk is associated with androgen receptor(AR)-CAG repeat and kallikrein-2 polymorphisms in Indian population but no unambiguous association was observed with PSA and AR-GGN repeat polymorphism PMID: 17257635
  23. role of kallikrein gene 2 and 3 variant SNPs in the etiology of prostate cancer among men of European ancestry PMID: 17593395
