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.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
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

Has a strict specificity for hydrolysis of asparaginyl bonds. Can also cleave aspartyl bonds slowly, especially under acidic conditions. Required for normal lysosomal protein degradation in renal proximal tubules. Required for normal degradation of internalized EGFR. Plays a role in the regulation of cell proliferation via its role in EGFR degradation. May be involved in the processing of proteins for MHC class II antigen presentation in the lysosomal/endosomal system.

  1. Studies identified Legumain (LGMN) as a new target which is highly expressed in the tumor microenvironment and in tumor cells. [review] PMID: 27993111
  2. our results suggest that M2 tumour-associated macrophages affect degradation of the extracellular matrix and angiogenesis via overexpression of legumain, and therefore play an active role in the progression of DLBCL. PMID: 27464733
  3. Legumain regulates oxLDL-induced macrophage apoptosis by enhancing the autophagy pathway. PMID: 29414692
  4. MiRNA-3978 regulates peritoneal gastric cancer metastasis by targeting legumain expression, promoting cell migration/neoplasm invasiveness. PMID: 27793040
  5. These results showed that Asparaginyl endopeptidase could promote invasion and metastasis by modulating epithelial-to-mesenchymal transition. PMID: 27102302

  8. Data suggest that melanoma cells internalize/absorb cystatin C from culture media, leading to increased intracellular cystatin C levels; cystatin E/M is internalized as well but at modest rate due to down-regulation of cell migration; however, the effect of intracellular cystatin E/M on down-regulation of legumain activity is pronounced.

  10. AEP promotes activation of the PI3K-AKT signaling pathway in prostate cancer cells. PMID: 27590439
  11. upregulation of legumain is associated with malignant behavior of uveal melanoma. PMID: 26846877
  12. Studies indicate that legumain, usually in lysosomes, is also found extracellularly and even translocates to the cytosol and the nucleus. PMID: 26403494

  14. Legumain appears to be involved in tumor development and deterioration. PMID: 26607955
  15. AEP acts as a delta-secretase, cleaving APP at N373 and N585 residues, selectively influencing the amyloidogenic fragmentation of APP. AEP contributes to the age-dependent pathogenic mechanisms in Alzheimer disease. PMID: 26549211
  16. High legumain expression is associated with breast cancer. PMID: 25605174
  17. This unique feature was confirmed by the crystal structure of AEPpH4.5 (AEP was matured at pH 4.5 and crystallized at pH 8.5), in which the broken peptide bonds were religated and the structure was transformed back to its proenzyme form. PMID: 24407422
