Function

Contributes to the lung's defense against inhaled microorganisms, organic antigens and toxins. Interacts with compounds such as bacterial lipopolysaccharides, oligosaccharides and fatty acids and modulates leukocyte action in immune response. May participate in the extracellular reorganization or turnover of pulmonary surfactant.

Biological Context

Subcellular Location: Secreted, extracellular space, extracellular matrix; Secreted, extracellular space, surface film
Tissue Specificity: Expressed in lung, brain, pancreas and adipose tissue (mainly mature adipocytes)

Product Specifications

Recombinant Human Pulmonary surfactant-associated protein D (SFTPD) is a recombinant protein from Homo sapiens (Human), expressed in Yeast, covering amino acids 21-375aa, with N-terminal 6xHis-tagged tag, molecular weight 35.2kDa, 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.
