生物活性

Thymic factor X (TFX-Jelfa) is an aqueous extract from juvenile calf thymuses and a natural stimulator of lymphocyte function[1][2].

体内研究
(In Vivo)

The percentage of necrotic lymphocytes in the spleen in Group I (infected with T. spiralis and treated with Thymus factor X (TFX)) is significantly lower than in the control group on day 7, and approximately the same as in the control group for the rest of the experiment. The percentage of necrotic lymphocytes in muscle tissue in Group I is approximately the same as in the control group on day 7, significantly lower on days 14 and 21 (p<0.0002), approximately the same on days 28 and 35, significantly lower on day 42, and significantly higher on day 60 (p<0.005)[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.

Animal Administration
[1]

The experiment is carried out using 134 mice divided into three groups: Group I: 46 mice infected with T. spiralis and treated with Thymus factor X (TFX); Group II: 42 uninfected mice treated with Thymus factor X; and Control group: 46 mice infected with T. spiralis and not treated with Thymus factor X. Thymus factor X is administered subcutaneously at a dose of 15 mg/kg. The first dose is administered on the third day before the mice are infected with T. spiralis. The dose is repeated at 24 h intervals until the thirteenth day after infection. In all, 17 doses are administered. On days 7, 14, 21, 28, 35, 42, and 60 after infection, six mice from each group are sacrificed using halothane. The spleen, mesenteric lymph nodes and masseter muscles are excised from each mouse and transferred to sterile phospho-buffered saline at 4°C[1].
