CAQK peptide
Based on 1 Customer Validation
CAQK peptide selectively binds to injured mouse brain. CAQK peptide selectively targets demyelinating areas and it is absent from healthy tissue. The CAQK peptide target is a proteoglycan complex upregulated in brain injuries and is used for drug delivery. CAQK peptide can penetrate the blood-brain barrier.

Description
In Vitro
FAM-CAQK selectively associates with focal and impact-induced brain lesions while not interacting with healthy brain and other tissues. At lesion sites, the peptide is primarily associated with the fibrous extracellular matrix (ECM) deposited in interstitial spaces proximal to reactive astrocytes[1][2].

-
Animal Model:C57BL/6J 8-week-old male mice[1]
-
Dosage:100 nmoles/100 μl in PBS
-
Administration:Tail vein; at 24 h or 5 days post-injury (focal demyelination was induced by stereotaxic injection of 1 μL of 1% lysolecithin solution into the right ventral)
-
Result:Caused the accumulation of peptide at the injury site by an increased density of mononucleated DAPI+ cells and fragmented myelin stained for myelin basic protein.
The peptide was not detected in the spinal cords of control sham-operated (PBS injected) mice showing regular densities of DAPI+ cells.

Solvant et solubilité
In Vitro:
H2O : ≥ 100 mg/mL (222.95 mM)
DMSO : ≥ 100 mg/mL (222.95 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
