生物活性

Arg-Gly-Asp-Cys is the binding motif of fibronectin to cell adhesion molecules, and can inhibit platelet aggregation and fibrinogen binding.

体外研究
(In Vitro)

RGDC immobilizes peptide onto DAH-CMTMC is found to be about 15.3 μg/mg of chitosan derivative by amino acid analysis (AAA). RGDC-functionalized chitosan may lead to enhanced wound healing (viability >140%). RGDC-functionalizes chitosan derivatives exhibit in vitro wound healing properties by enhancing fibroblast proliferation and adhesion. RGDC-DAH-CMTMC favors cell growth and an increase in cellular proliferation compared to the control cells[1].

Peptide Solubility and Storage Guidelines:

1.;;Calculate the length of the peptide.

2.;;Calculate the overall charge of the entire peptide according to the following table:

; Contents Assign value
Acidic amino acid Asp (D), Glu (E), and the C-terminal -COOH. -1
Basic amino acid Arg (R), Lys (K), His (H), and the N-terminal -NH2 +1
Neutral amino acid Gly (G), Ala (A), Leu (L), Ile (I), Val (V), Cys (C), Met (M), Thr (T), Ser (S), Phe (F), Tyr (Y), Trp (W), Pro (P), Asn (N), Gln (Q) 0

3.;;Recommended solution:

Overall charge of peptide Details
Negative (lt;0) 1.;;Try to dissolve the peptide in water first.
2.;;If water fails, add NH4OH (lt;50 μL).
3.;;If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide.
Positive (gt;0) 1.;;Try to dissolve the peptide in water first.
2.;;If water fails, try dissolving the peptide in a 10%-30% acetic acid solution.
3.;;If the peptide still does not dissolve, try dissolving the peptide in a small amount of DMSO.
Zero (=0) 1.;;Try to dissolve the peptide in organic solvent (acetonitrile, methanol, etc.) first.
2.;;For very hydrophobic peptides, try dissolving the peptide in a small amount of DMSO, and then dilute the solution with water to the desired concentration.

Cell Assay
[1]

Human precursor dermal fibroblasts (HDF, human dermal progenitor cells, 12 week male donor) are use in the assay. WST-1 assay is used to assess the viability of HDF when incubated with chitosan derivatives. For this study, HDF are seeded in a 96-well plate at a density of 6×103 cells/cm2. To each well, 100 μL of cell suspension is added and incubated for 48 h in order to allow cell attachment. DMEM is then replaced by 100 μL of CMTMC and RGDC-DAH-CMTMC suspension at concentrations of 0.25 mg/mL, 0.5 mg/mL and 1 mg/mL, respectively. Cell viability under polymer incubation is evaluated during 2, 4 and 7 days. SDS (1%) is used as negative control. The polymer solution is changed every 3 days. 100 μL of WST-1 (1:10 dilution in DMEM) are added in each well after removing the polymer suspension and incubated for 0.5-2 h. Absorbance is recorded with a BioTek Microplate reader at two different wavelengths (450 and 690 nm). The viability is presented as percentage compared to the positive control group (cells in DMEM supplemented with 10% fetal calf serum). All experiments are carried out in triplicates.
