CKS9
Based on 1 Customer Validation
CKS9 is an M cell-targeting polypeptide with the amino acid sequence CKSTHPLSC, forming a 9-mer peptide via cyclization through a disulfide bond between the two cysteine residues. CKS9 is obtained through phage display technology screening and has high affinity for M cells. CKS9 can promote chitosan nanoparticles to cross M cells and enter the follicle-associated epithelium (FAE) of intestinal Peyer's patches (PP). CKS9 can be used in studies related to swine dysentery and oral delivery.

Biologische Aktivität
Beschreibung
In Vitro
CKS9 can be successfully grafted onto stearic acid esterified starch to form SES@CKS9-1 and SES@CKS9-2[1].
CKS9-modified SES exhibits stronger binding affinity to integrin α5β1 than unmodified SES. CKS9 mediates key hydrogen-bond interactions at the interface of the βI/β-propeller domain of integrin, suggesting that integrin α5β1 is a potential M cell receptor for CKS9[1].
CKS9 is conjugated with WSC via EDC/NHS, with a molar ratio of 6.37 mol%[2].
As the C-terminal component of a computationally designed multi-epitope oral vaccine against *Helicobacter pylori*, CKS9 targets intestinal epithelial microfold cells to enhance the intestinal barrier uptake of the vaccine[3].

Lösungsmittel & Löslichkeit
In Vitro:
DMSO : 20 mg/mL (20.55 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
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.

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2 mg/mL (2.06 mM); Clear solution
This protocol yields a clear solution of ≥ 2 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2 mg/mL (2.06 mM); Clear solution
This protocol yields a clear solution of ≥ 2 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
