Recombinant Human Serpin Peptidase Inhibitor, Clade B Member 4 is supplied as a recombinant protein for in vitro research use.

Background

Serpin Peptidase Inhibitor, Clade B Member 4, also known as SERPINB4 is a member of the serpin family. SERPINB4 acts as a protease inhibitor to modulate the host immune response against tumor cells. Among the diseases associated with SERPINB4 are: inverted papilloma as well as burns.

Product format

Provided as a recombinant protein suitable for in vitro workflows such as binding studies, screening, and assay development. Refer to the specifications table for expression format and molecular properties.

What is the purity of Recombinant Human Serpin Peptidase Inhibitor, Clade B Member 4 (Human)?
Greater than 90.0% as determined by SDS-PAGE. BioHippo includes a Certificate of Analysis (CoA) confirming purity per lot with every order.
What buffer / formulation is this protein supplied in?
Supplied as: SERPINB4 protein solution (0.5mg/ml) containing Phosphate buffered saline (pH7.4), 10% glycerol and 1mM DTT. Reconstitute lyophilized material in sterile ultrapure water or the recommended buffer per the datasheet prior to use.
How should Recombinant Human Serpin Peptidase Inhibitor, Clade B Member 4 (Human) be stored?
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid multiple freeze-thaw cycles. Prepare single-use aliquots after reconstitution to avoid repeated freeze–thaw cycles.
What expression system was used to produce this protein?
This recombinant protein was expressed in E. coli. The system was selected to achieve high yield, correct folding, and appropriate post-translational modifications.
Is this protein approved for clinical or in vitro diagnostic use?
No. Supplied for Research Use Only (RUO) — not intended for therapeutic applications or in vitro diagnostic procedures.
Can I request a custom size, tag variant, or formulation?
Yes. BioHippo can accommodate custom requests including alternative sizes, His/GST/Fc tag variants, bulk quantities, and custom formulations. See the Customization & Add-ons tab or email support@biohippo.com.
