Tag Info
N-terminal 6xHis-SUMO-tagged
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.
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 region for expressing recombinant Human SERPINB4 contains amino acids 1-390. The theoretical molecular weight of the SERPINB4 protein is 60.9 kDa. The SERPINB4 protein was expressed in e.coli. The SERPINB4 coding gene included the N-terminal 6xHis-SUMO tag, which simplifies the detection and purification processes of the recombinant SERPINB4 protein in following stages of expression and purification.
Serpin B4 (SERPINB4), a member of the serine protease inhibitor (serpin) superfamily, plays a role in regulating proteolytic processes. SERPINB4 is primarily expressed in squamous epithelial tissues and has been implicated in various physiological and pathological conditions. SERPINB4 is known to inhibit specific serine proteases, thereby modulating processes like inflammation, tissue remodeling, and immune response. Research on SERPINB4 includes investigations into its involvement in cancer, particularly in squamous cell carcinomas, where its dysregulation may contribute to tumor progression and metastasis. Understanding the functions and regulatory mechanisms of SERPINB4 can provide insights into its potential as a therapeutic target in diseases associated with aberrant protease activity.
