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

Description

The generation of the recombinant Human STOM protein typically includes the following steps: synthesizing the recombinant plasmid containing the gene encoding the Human STOM protein (1-288aa), transforming the recombinant plasmid into e.coli cells, selecting the positive e.coli cells, and culturing the positive e.coli cells for protein expression. The protein is equipped with a N-terminal 6xHis-SUMO tag. After expression, affinity purification is employed to isolate and purify the recombinant STOM protein from the cell lysate. Denaturing SDS-PAGE is utilized to resolve the resulting recombinant Human STOM protein, revealing a purity level exceeding 90%.

Target Background

Function
Regulates ion channel activity and transmembrane ion transport. Regulates ASIC2 and ASIC3 channel activity.
Gene References into Functions
  1. we show that stomatin modulates the transport activity of AE1 through a direct protein-protein interaction. PMID: 28387307
  2. These results may suggest that stomatin is a new prognostic indicator for HER2-positive breast cancer PMID: 27577936
  3. FRAP analyses indicate that the stomatin C-terminus is the dominant entity for lateral mobility and binding site for the cortical actin cytoskeleton PMID: 28575093
  4. This study showed that cells expressing more stomatin or exposed to exogenous stomatin are more prone to undergoing cell fusion; during osteoclastogenesis, depletion of stomatin inhibited cell fusion but had little effect on tartrate-resistant acid phosphatase production. PMID: 27663861
  5. Authors took a proteomic approach to identify stomatin, a member of the integral proteins of lipid rafts, as a cellular protein interacting with hepatitis C virus NS5B. PMID: 25262680
  6. Stomatin protein expression is down-regulated in 80% of non-small cell lung cancer samples. PMID: 24533441
  7. upregulation of stomatin by hypoxia and dex may enhance the barrier function of alveolar epithelia and mediate the adaptive role of glucocorticoid to hypoxia PMID: 23672602
  8. Stomatin interacts with GLUT1/SLC2A1, band 3/SLC4A1, and aquaporin-1 in human erythrocyte membrane domains PMID: 23219802
  9. [review] Stomatin family member STOM is oligomeric; it localizes mostly to membrane domains and has been shown to modulate ion channel activity. PMID: 21501885
  10. The study indicates that stomatin, sorcin, and synexin are echinophilic membrane components that mainly locate outside GM1 rafts in the human erythrocyte membrane. PMID: 20858460
  11. This study demonstrated the existence of alpha-granular lipid rafts and suggests an important role for stomatin in the organization and function of alpha granules. PMID: 12130500
  12. stomatin is localized to detergent-insoluble domains of neutrophil granule membranes PMID: 12429719
  13. in stomatocytosis there is no significant abnormality in stomatin gene sequence instead, deficiency of stomatin from red cells appears to be due to a loss of stomatin from these red cells on maturation in the bone marrow and in the circulation. PMID: 12750157
  14. study of strongly homologous stomatin-like genes in prokaryotes reveals a close connection with a gene coding for a hydrophobic protein with a probable serine protease motif; stomatin could be a partner protein for a membrane-bound proteolytic process PMID: 15121101
  15. stomatin binds to and alters the gating of acid-sensing ion channels PMID: 15471860
  16. A small C-terminal region of stomatin that is largely hydrophobic (residues 264-272) is crucial for oligomerization, whereas the N-terminal domain (residues 1-20) and the last 12 C-terminal amino acids (residues 276-287) are not essential. PMID: 16766530
  17. The stomatin-actin association is important in maintaining the structure and in modulating the function of stomatin-containing membrane rafts in red cells. PMID: 17961506
  18. Data indicate that a stomatin-specific, raft-based process is involved in storage-associated vesiculation. PMID: 18067507
  19. Stomatin-like protein-1 interacts with stomatin and is targeted to late endosomes PMID: 19696025
  20. Stomatin is a member of an ancient protein family that has extremely well conserved homologues in all three domains of life. PMID: 18267007
