Description

  Product Detail

Basic Parameter Information

Full Name: Selank

Amino Acid Sequence: H-Thr-Lys-Pro-Arg-Pro-Gly-Pro-OH

Molecular Formula: C₃₃H₅₇N₁₁O₉

Molecular Weight: 751.87 g/mol

CAS Number: 129954-34-3

Appearance: Sterile lyophilized white crystalline powder, individually packed and sealed in vials (main specifications: 5mg / 10mg / 50mg)

Purity: ≥99% tested and verified by HPLC, each batch is attached with full COA quality inspection documents

R&D Background: Selank is a synthetic heptapeptide derived from tuftsin, developed for laboratory research on central nervous system balance and immune regulation. This artificially synthesized peptide features optimized amino acid sequences to enhance structural stability and sustained biological activity. The high-purity lab-grade raw material is designed for primary neuron culture, neurotransmitter pathway exploration, chronic stress cell model testing and neuroimmune interaction research, widely used in neurobiology, neurotrophic factor study and cerebral tissue cell experimental projects.

2. Core Mechanism of Action

Selank acts on neural cells and resident immune cells in nervous tissue, regulating multiple interrelated signal pathways to stabilize cellular physiological state within in vitro culture environments:

Optimize the transmission efficiency of inhibitory neurotransmitter signals on hippocampal and cortical neurons, relieve excessive excitatory activity of nerve cells triggered by simulated stress culture conditions;

Promote the production and accumulation of endogenous neurotrophic factors in neural precursor cells, support the formation and repair of synaptic structures to maintain stable signal communication between neuron populations;

Moderate the breakdown rate of endogenous neuropeptides linked to emotional regulation, maintain balanced levels of mood-regulating signal substances inside neural tissue co-culture samples;

Adjust the secretion volume of inflammatory signaling molecules from glial cells, suppress abnormal inflammatory reactions in the local microenvironment of brain tissue and reduce long-term inflammatory damage to neuronal structures;

Improve the survival capacity of primary neurons during long-term culture, ease functional decline caused by oxidative stimulation and overexcitation of nerve cell receptors;

Coordinate signal exchange between neurons and microglia cells, rebuild a mild and balanced microenvironment for mixed cerebral cell culture systems under continuous external stimulation.

3. Core Research Efficacy (For Research Laboratory Use Only)

Neurotransmitter Balance & Neural Excitability Research

Core experimental probe for culturing hippocampal and cortical neurons, suitable for quantitative detection of inhibitory signal pathway activity and neural excitability adjustment assays.

Neurotrophic Factor & Synaptic Remodeling Research

Key experimental raw material for analyzing neurotrophic factor expression rules, supporting cell-level exploration of synaptic structure reconstruction and neural signal storage mechanisms.

Chronic Stress Neural Dysfunction Cell Model Research

Auxiliary testing reagent for cell systems simulating sustained stress stimulation, applied to research on emotional regulatory neurotransmitter metabolic balance.

Neuroimmune Crosstalk & Neuroinflammation Research

Balance disordered cytokine output in neuron-glia co-culture systems, ideal for laboratory exploration of mild chronic inflammatory damage relief in nervous tissue.

Primary Neural Cell Long-Term Culture Protection Research

Sustain stable vitality of isolated neural precursor cells, support mechanism study of oxidative stress and overexcitation induced neuronal aging and damage recovery.

Supplied as sterile lyophilized white crystalline powder with HPLC-certified purity ≥99%, common vial specifications cover 5mg, 10mg and 50mg. Every batch includes complete supporting materials such as COA, MSDS and HPLC chromatogram test records.

As a dual-function neuroprotective and immune-regulatory heptapeptide laboratory reagent, Selank combines the advantages of stabilizing neural excitability, boosting neurotrophic expression and relieving neuroinflammation. Its short-chain polypeptide structure offers excellent cell permeability and steady target regulatory activity for various in vitro neuron, glia and mixed cerebral tissue culture research systems.

It serves as essential research material for cell cultivation and tissue model experiments covering central nervous signal transmission, synaptic plasticity, neuroimmune balance and stress-related neuronal functional impairment research.

Note: For laboratory research use only, not approved for human oral consumption or clinical therapeutic treatment.
