Application
Flow cytometry: 1-10 μg/mL, with incubation for 30 minutes at 4°C. Daudi or L929 cells may be used as negative controls.
Induction of apoptosis with SM1/1:
SM1/1 induces apoptosis best when used together with a 10 molar excess of crosslinking anti-mouse IgG. The amount of antibody needed will vary depending upon the cell line used and the age of the cell and their growing conditions; best results are achieved when cells are less than 70% confluent and relatively young passage numbers, and note not all cells what express CD95 can be induced with SM1/1, the reasons why are unclear.
On Jurkat cells 100-500ng/mL of SM1/1 in the presence of 10X excess of goat anti-mouse IgG will produce ~50% kill as measured by MTT assay; without crosslinking, little or no killing will be observed.
On SKw6.4 cells 100-500ng/mL of SM1/1 in the presence of 10X excess goat anti-mouse IgG will produce ~50% kill as measured by MTT; without crosslinking ~20% or less of the cells will be induced.
On L/F15 cells 100-500ng/mL of SM1/1 with or without crosslinking IgG ~ 50% of the cells will be induced to undergo apoptosis as measured by MTT assay.
In all cases it is important to remove excess SM1/1 before adding the secondary crosslinking antibody;
Antibody additions can be either at 4C, or 37C; at 37C primary antibody should be incubated no longer than two hours prior to secondary crosslinker addition. Crosslinking antibody is typically incubated overnight, although shorter times may yield acceptable results.
As controls, cells should be incubated with an unrelated irrelevant isotype matched IgG2a antibody or with the crosslinking antibody alone.
SM1/1 monoclonal characterization is first reported in Trauth, BC et al Science 1989 245:301-5.
Optimal working dilutions must be determined by end user.
