| Solubility | Centrifuge the vial before adding solvent (10,000 x g for 5 minutes) to spin down all the powder to the bottom of the vial. The lyophilized product may be difficult to visualize. Add solvent directly to the centrifuged vial. Tap the vial to aid in dissolving the lyophilized product. Tilt and gently roll the liquid over the walls of the vial. Avoid vigorous vortexing. Light vortexing for up to 3 seconds is acceptable if needed. For long-term storage in solution, we recommend preparing a stock solution by dissolving the product in sterile water at a concentration of at least 0.1 mg/mL. Divide the stock solution into small aliquots and store at -20°C. Before use, thaw the relevant vial(s) and dilute to the desired working concentration in your working buffer. It is recommended to prepare fresh solutions in working buffers just before use. Repeat freeze-thawing may result in loss of activity. |

Overview
Recombinant human Artemin protein is a research-grade protein/peptide reagent used in research settings. It is commonly applied as a tool reagent related to GFRa3 biology and/or assay development. It is supplied in Lyophilized format to support flexible downstream use in RUO workflows. Researchers commonly pair it with applications such as Western blot.
Key elements and design rationale
- Molecular identity: MW: 23.9 kDa (dimer).
- Source / origin: Recombinant, E. coli.
- Quality attributes: Purity: ≥98% (HPLC); Bioassay tested: Yes; Sterile / endotoxin-free: Yes.
Modifications
Inter-chain disulfide bonds between Cys16-Cys81, Cys43-Cys109, Cys47-Cys111 and intra-chain disulfide bond between Cys80 of two hArtemin molecules.
When used as a biochemical or pharmacological tool, results are best interpreted relative to the experimental system (species, expression level, and assay readout) and with appropriate negative and competition-style controls where relevant. This product is intended for research use only.
Biological background
Artemin (ART), also named enovin and neublastin, is a neurotrophic factor that is crucial for the proper development of the sympathetic nervous systeM ART belongs to the glial cell line-derived neurotrophic factor (GDNF) family of ligands, which also includes GDNF, neurturin (NRTN), and persephin (PSPN). Artemin mRNA is expressed in many human adult and fetal tissues and in rat Schwann cells. Artemin's activity is mediated by a receptor complex composed of a receptor tyrosine kinase signaling component, RET, which is common for all GFLs, and a specific anchored membrane protein, GFRα3. Experimental studies have suggested that artemin supports the survival of cultured neurons from the dorsal root, trigeminal, nodose, and superior cervical ganglia and that it affects neurite outgrowth from the dorsal root and sympathetic ganglia of murine embryos. Recent investigations have reported that systemic artemin prevents and reverses neuropathic pain1.
Research relevance and current trends
- Using high-specificity ligands, toxins, and engineered peptides to dissect closely related receptor/channel subtypes and signaling microdomains.
- Pairing labeled (e.g., fluorescent) proteins/peptides with advanced imaging to map surface expression, trafficking, and nanoscale organization.
- Increasing emphasis on reproducibility through standardized characterization (identity, purity, and lot QC) and transparent reporting of reagent attributes.
Common research applications
- Western blot: commonly used to compare signal, binding, or functional readouts across conditions without implying a specific protocol.
Across these use cases, changes in signal or functional readout are generally interpreted as evidence of differences in target abundance, accessibility, or engagement, but alternative explanations (matrix effects, off-target interactions, or assay artifacts) should be considered.
Notes for experimental interpretation
- Assay context matters: binding assays, functional modulation, and detection workflows can yield different readouts even for the same target system.
- Target complexity: closely related family members, splice variants, and post-translational modifications can influence apparent specificity and potency.
- Matrix and sample effects: buffer composition, detergents, and biological matrices may alter stability or apparent activity; interpret with appropriate controls.
- Control concepts: include negative controls and orthogonal validation (e.g., genetic perturbation or alternative reagents) to support robust interpretation.
