Form

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

Lyophilized from a 0.2 μm filtered 20 mM Tris-HCl, 0.5 M NaCl, 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

Protein 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

Basically, we can dispatch the products out in 3-7 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.

Notes

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

Description

MUC17 plays a critical role in epithelial barrier protection within the gastrointestinal tract, and this recombinant partial construct (aa 4131–4390) captures a functionally relevant segment of the extracellular domain. Activity validation by functional ELISA demonstrates robust antibody-binding capacity, with an EC50 of 0.91–1.26 ng/mL against a recombinant anti-MUC17 antibody when immobilized at 2 μg/mL — a result that supports use in antibody screening, epitope mapping, and sandwich ELISA development. Produced in mammalian cells with a C-terminal 10×His tag, this protein retains native-like post-translational modifications essential for accurate binding studies. Purity exceeding 95% by SDS-PAGE combined with endotoxin levels below 1.0 EU/μg satisfies the criteria typical for both cell-based functional assays and as a reliable positive control in immunoassay optimization workflows.
