Function

ATP-dependent RNA helicase involved in mRNA export from the nucleus. Rather than unwinding RNA duplexes, DDX19B functions as a remodeler of ribonucleoprotein particles, whereby proteins bound to nuclear mRNA are dissociated and replaced by cytoplasmic mRNA binding proteins.

Biological Context

Subcellular Location: Cytoplasm; Nucleus, nucleoplasm

Product Specifications

Recombinant Human ATP-dependent RNA helicase DDX19B (DDX19B) is a recombinant protein from Homo sapiens (Human), expressed in E.coli, covering amino acids 2-479aa, with N-terminal 6xHis-SUMO-tagged tag, molecular weight 66.7kDa, 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.
