Biological background
Protein function (datasheet): In presence of calcium ions, it binds to surfactant phospholipids and contributes to lower the surface tension at the air-liquid interface in the alveoli of the mammalian lung and is essential for normal respiration.
Scientific background (datasheet): Surfactant protein A is an innate immune system collectin. The gene encoding SP-A map to mouse chromosome 14. Surfactant protein-A, which plays a role in innate host defense in the lung, is also expressed in the Eustachian tube. We report that the frequency of specific surfactant protein-A haplotypes and genotypes differs between children with recurrent otitis media compared with a control population.
Cellular localization (datasheet): Secreted, extracellular space, extracellular matrix. Secreted, extracellular space, surface film.
Sequence similarities (datasheet): Belongs to the SFTPA family.
Research relevance and current trends
- Commonly studied in contexts related to Cytoskeleton/ECM,ECM Proteins,Extracellular Matrix,Signal Transduction.
- Supports comparative expression analysis across conditions, genotypes, or treatments when paired with appropriate controls.
- Useful for confirming target presence and subcellular distribution using orthogonal readouts (e.g., microscopy vs. immunoblotting).
Common research applications
- Western blot (WB): Compare relative target abundance and apparent size/isoforms across samples; interpret bands in light of expected MW and potential PTMs.
- ELISA: Measure target abundance in compatible matrices using a standard-curve readout; ensure dilution linearity and appropriate controls.
- Immunohistochemistry (IHC): Assess tissue distribution and cell-type patterns; interpret staining with appropriate negative controls and antigen context.
- Flow cytometry: Quantify target-positive populations in single-cell suspensions; pair with viability and isotype/FMO controls conceptually.
Notes for experimental interpretation
- Consider isoforms, post-translational modifications, and processing that can shift apparent molecular weight or localization.
- Cross-reactivity (datasheet): No cross-reactivity with other proteins
- Use appropriate positive and negative controls (e.g., KO/KD, blocking peptide, or isotype controls) to support specificity interpretation.
As a polyclonal antibody, this reagent may recognize multiple epitopes on the target, which can improve detection robustness but may require careful specificity controls.
