Research AreasImmunology

Function

Promotes absorption of the essential vitamin cobalamin (Cbl) in the ileum. After interaction with CUBN, the CBLIF-cobalamin complex is internalized via receptor-mediated endocytosis.

Biological Context

Subcellular Location: Secreted
Tissue Specificity: Gastric mucosa
Disease Association: Hereditary intrinsic factor deficiency (IFD) : Autosomal recessive disorder characterized by megaloblastic anemia. [The disease is caused by variants affecting the gene represented in this entry]

Product Specifications

Recombinant Human Cobalamin binding intrinsic factor (CBLIF) is a recombinant protein from Homo sapiens (Human), expressed in Yeast, covering amino acids 19-417aa, with N-terminal 6xHis-tagged tag, molecular weight 45.4kDa, purity Greater than 90% 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.
