Potential Applications in Research (RUO)

Strictly for laboratory research. No health, diagnostic, or therapeutic claims are made or implied.

Transcriptome-level modulation assays: Use AEDP in cell or tissue models with cDNA microarray / RNA-seq follow-up to profile differentially expressed genes (e.g., mitochondrial, signaling, stress-response). :contentReference[oaicite:0]{index=0}
Neurite outgrowth & axon biology: Evaluate effects on neurite extension, growth-cone dynamics, or conduction markers in neuron-like cells or ex vivo explants (e.g., DRG), informed by prior sciatic-nerve regeneration studies. :contentReference[oaicite:1]{index=1}
Oxidative-stress & mitochondrial panels: Quantify ROS, ΔΨ_m, and expression of ETC genes (e.g., COX3, ND5) under defined stressors to map AEDP-linked pathways. :contentReference[oaicite:2]{index=2}
Inflammation/cytokine readouts: In glial or mixed neuro-immune co-cultures, measure cytokine profiles and signaling nodes to assess pathway directionality in vitro. :contentReference[oaicite:3]{index=3}
Chromatin/epigenetic screens: Explore chromatin accessibility or heterochromatin marks (e.g., ATAC-seq, H3K9me3 IF) to test short-peptide impacts on nuclear organization suggested for bioregulators. :contentReference[oaicite:4]{index=4}

Quality, Handling & Safety

Verification: Each lot is tested by independent U.S. labs for purity, quantity, and endotoxin; results are accessible via the QR on the vial label.
Reconstitution: Use sterile water or a suitable buffer; for working stocks, include an inert carrier (e.g., 0.1% BSA) when adsorption is a concern.
Aliquoting: Prepare single-use aliquots; avoid freeze–thaw cycles.

Shipping & Fulfillment

Orders ship in validated cold-chain packaging. In-stock vials ship the same business day before cutoff. 2-Day FedEx/UPS is standard; discounted overnight is available. International shipping offered where permitted; automated text/email status updates included.

FAQs

Is Cortagen the same as Cortexin?: No. Cortexin is a heterogeneous protein extract; Cortagen is a defined tetrapeptide (AEDP) synthesized by SPPS and characterized by HPLC/MS. :contentReference[oaicite:8]{index=8}
What documentation comes with each vial?: Every vial is linked to a COA via on-label QR code, including identity (MS), purity (HPLC), quantity, endotoxin, and storage guidance.
How should I design in-vitro work with AEDP?: Start with concentration-response curves in your system, include vehicle controls, and measure pre-specified endpoints (e.g., RNA-seq, ROS, neurite metrics) with appropriate replicates and statistics. See the cited microarray and regeneration literature for model selection. :contentReference[oaicite:9]{index=9}
