    Descripciòn

    Pam3CSK4 TFA 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 (MRSA)[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.

    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.
