溶解性数据 | In Vitro: H2O 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 (<0) | 1. Try to dissolve the peptide in water first. 2. If water fails, add NH4OH (<50 μL). 3. If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide. | Positive (>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. |

体内研究 | RC-3095 impairs aversive but not recognition memory in Wistar male rats. RC-3095 (0.3 mg/kg or 1 mg/kg; S.C.) shows anti-inflammatory effects in 2 experimental models of arthritis, collagen-induced arthritis (CIA) and antigen-induced arthritis (AIA). Arthritic mice treated with RC-3095 show a significant reduction in the concentrations of IL-17, IL-1 , and TNF, and showed a diminished expression of GRPR. XIYU has not independently confirmed the accuracy of these methods. They are for reference only. Animal Model: | Male Balb/c wild-type mice (weighing 18-25 gm) with AIA model; Male DBA/1J inbred mice (weighing 18-25 gm) with CIA model | Dosage: | 1 mg/kg for AIA studies; 0.3 mg/kg or 1 mg/kg for CIA studies | Administration: | Injected SC twice a day for a total of 2 or 10 days for AIA studies; Administered SC twice a day for 10 days after the onset of the disease for CIA studies | Result: | Reduced neutrophil migration, mechanical hy pernociception, and proteoglycan loss in mice with AIA; Led to a significant reduction in arthritis clinical scores and the severity of disease in the CIA model. |
