生物活性

KSPWFTTL is an immunodominant Kb-restricted epitope from the p15E transmembrane protein. KSPWFTTL can restore susceptibility of a tumor line to anti-AKR/Gross MuLV cytotoxic T lymphocytes[1][2].

体外研究
(In Vitro)

KSPWFTTL is derived from the retroviral p15 TM envelope protein. The cytolytic T-lymphocyte (CTL)-insusceptible, variant cl.18-5 clonal line, after pulsed with the KSPWFTTL peptide, becomes susceptible to lysis by antiviral CTL[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

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.
