Liquid or 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.
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
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°C/-80°C. 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
3-7 business days
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Component of the proteolytic cascade acting downstream of the 26S proteasome in the ubiquitin-proteasome pathway. May be able to complement the 26S proteasome function to some extent under conditions in which the latter is inhibited. Stimulates adipogenesis.

  8. Current knowledge about TPPII with a focus on structural aspects. PMID: 21771670
  9. Results suggest an important function of TPPII in the maintenance of viral growth and may have implications for anti-viral therapy. PMID: 21134372
  10. the promoter could be localized to a 215 bp fragment upstream of the initiation codon. PMID: 15716107
  11. TPPII appears to promote malignant cell growth by allowing exit from mitosis and the survival of cells with severe mitotic spindle damage. PMID: 16762321
  12. TPP2 plays a specialized role in antigen processing and one that is not essential for the generation of most presented peptides. PMID: 16849449
  13. This investigation reveals that TPP II expression could be regulated through both positive and negative regulatory elements. PMID: 17343995
  14. Expression of mRNA for MuRF-1 increased approximately 3-fold at 10 days without changes in MAFbx or tripeptidyl peptidase II mRNA, but all decreased between 10 and 21 days of muscle disuse. PMID: 17901116
  15. Results indicate that TPPII is dispensable for the generation of proteasome-dependent HLA class I ligands and, the enzyme is not involved significantly in generating the proteasome-independent HLA-B27-bound peptide repertoire. PMID: 18286573
  16. Cross-presentation of NY-ESO-1/ISCOMATRIX cancer vaccine was proteasome independent and requires the cytosolic protease tripeptidyl peptidase II. PMID: 19155470
  17. MHC class I-restricted LMP1 epitopes studied in this work are two of very few epitopes known to date to be processed proteasome independently by tripeptidyl peptidase II. PMID: 19587004
