Biological Context

Subcellular Location: Cell membrane (Single-pass type I membrane protein)
Tissue Specificity: Highly expressed in kidney, lung, placenta, stomach, skeletal muscle, colon and small intestine. Isoform A is prevalently expressed in the lung, testis, placenta, stomach and colon. Isoform B is more abundant in the brain, kidney and the liver. Isoform C is not detected in brain, heart, liver, kidney and skeletal muscle. Expressed on T-cells in fibrotic liver; at protein level. Overexpressed in fibrotic and cirrhotic liver

Product Specifications

Recombinant Human IL1RL1 / ST2 Protein is a recombinant protein, expressed in HEK293 Cells, covering amino acids 1-328aa, with C-His tag, molecular weight 36.5 kDa, purity Greater than 85% as determined by SDS-PAGE.. Suitable for ELISA and Western Blot applications.

SDS-PAGE: Single band at expected molecular weight confirming purity.

ELISA: Suitable as coating antigen or detection standard.

Western Blot: Compatible with standard Western Blot protocols.

Protein Interaction: Validated for SPR (Surface Plasmon Resonance) and BLI (Bio-Layer Interferometry) studies.

Shipping: Shipped at ambient temperature. Lyophilized protein is stable during transit.

Storage: Store lyophilized protein at -20°C to -80°C. Reconstituted protein should be aliquoted and stored at -80°C. Avoid repeated freeze-thaw cycles.

Shelf Life: 12 months from date of receipt when stored as recommended.

Shipping Time: Orders placed before 2 PM EST ship same day. International orders typically deliver within 5-10 business days.

Subunit

Interacts with MYD88, IRAK1, IRAK4, and TRAF6. Bound to its ligand IL-33, interacts with IL1RAP to form the minimal interleukin-33 signaling complex with a 1:1:1 stoichiometry. Interacts with KIT (bound to KITLG/SCF). A mast cell-specific KITLG/SCF-induced interleukin-33 signaling complex contains IL1RL1, IL1RAP, KIT and MYD88. Interacts with TMED1 (PubMed:23319592)

Frequently Asked Questions

How do I order or inquire about this product?

Fill out the Online Inquiry form with your required quantity and specifications. You can also email sales@biocrestsci.com. Our team typically responds within 4 business hours with a quote and availability confirmation.

What is the shipping and delivery time?

Orders placed before 2 PM EST ship the same day. Domestic (US) delivery typically takes 2-3 business days. International orders deliver within 5-10 business days. All products are shipped at ambient temperature with appropriate packaging to ensure stability.

How should I store this recombinant protein?

Lyophilized proteins should be stored at -20°C to -80°C upon receipt. After reconstitution, aliquot and store at -80°C. Avoid repeated freeze-thaw cycles. Shelf life is 12 months from date of receipt when stored as recommended.

What quality controls are performed on your products?

Each product undergoes SDS-PAGE purity analysis (typically >85-95%), endotoxin testing, and bioactivity validation. Products are validated for ELISA, Western Blot, and SPR/BLI applications as specified on this product page. A Certificate of Analysis (CoA) is available upon request.
