Pam3CSK4 is a toll-like receptor 1/2 (TLR1/2) agonist with an EC50 of 0.47 ng/mL for human TLR1/2.

At equivalent molar concentrations, both the salt and free forms of a compound exhibit comparable biological activity. Nevertheless, the salt form (Pam3CSK4 TFA) usually boasts enhanced water solubility and stability.

Description

Pam3CSK4 is a toll-like receptor 1/2 (TLR1/2) agonist with an EC50 of 0.47 ng/mL for human TLR1/2[1].

IC50 & Target

TLR1

 

TLR2

 

In Vitro

Pam3CSK4 is a TLR1/2 heterodimer recognises triacylated lipopeptides[1].
Pam3CSK4 (1 μg/mL) enhances the antibacterial functions of granulocyte macrophage-colony stimulating factor (GM-CSF) induced neutrophils to Methicillin-resistant Staphylococcus aureus[2].

In Vivo

Pam3CSK4 (5 mg/kg; i.p.; once a day for 9 days) alters brain, spleen and liver weights in neonatal mice[3].

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

Animal Model: Time-mated pregnant C57BL/6 wild-type mice; B6.129-Tlr2tm1Kir/J (TLR2 -deficient) mice[3]
Dosage: 5 mg/kg
Administration: Intraperitoneally (i.p.); once a day for 9 days
Result: After repeated administration from postnatal day (PND3) to PND11, brain weight was decreased compared with endotoxin-free saline-treated animals at PND12. Decreased volume of cerebral gray matter, white matter in the forebrain and cerebellar molecular layer that was accompanied by an increase in spleen and liver weight at PND12.

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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
