    Effects of FOLFOX on surface PD-L1 expression on AGS cells. Cells were treated with FOLFOX (Leucovorin: 14 μM; 5-Fu: 200 μM; Oxaliplatin: 6 μM) for 48 h. Then, cells were co-stained with annexin V and PD-L1 antibody. Representative histogram showing surface PD-L1 expression. Red histogram: total cells. Purple histogram: annexin V-positive cells.

    Description

    Folinic acid (Leucovorin) calcium hydrate is a biological folic acid and is generally administered along with Methotrexate (HY-14519) as a rescue agent to decrease Methotrexate-induced toxicity[1].

    IC50 & Target

    Human Endogenous Metabolite

     

    In Vitro

    Methotrexate (MTX) alone induces a concentration-related increase in % micronucleated binucleated cells (MNBN) and % aberrant cells (Abs). There is a decrease in nuclear division index (NDI) with increase in MTX concentration. Similarly, the mitotic index (MI) also decreases in all concentrations of MTX tested. The addition of Folinic acid calcium hydrate at 50 μg/ mL significantly reduces % MNBN (40-68%) and % Abs (36-77%). Inhibition is also seen at 5 μg/ mL Folinic acid calcium hydrate (12 to 54% for MNBN and 20 to 61% for Abs) [1].

    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.
