WB
Western blot analysis of Myc tag on different lysates with Mouse anti-Myc tag antibody at 1/100,000 dilution.
Lane 1: 293T transfected with Myc-tagged empty control cell lysate,
Lane 2: 293T transfected with Myc-tagged Claudin18.2 (C-terminal) cell lysate,
Lane 3: 293T transfected with Myc-tagged Histone H3.1 (N-terminal) cell lysate,
Lysates/proteins at 10 µg/Lane.
Exposure time: 1 minute 2 seconds;
4-20% SDS-PAGE gel.
Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody at 1/100,000 dilution was used in 5% NFDM/TBST at 4℃ overnight. Goat Anti-Mouse IgG - HRP Secondary Antibody at 1/50,000 dilution was used for 1 hour at room temperature.
ICC/IF
Immunocytochemistry analysis of 293T cells labeling Myc tag with Mouse anti-Myc tag antibody at 1/1,000 dilution.
293T cells, transfected with Myc-tagged empty control, Claudin18.2 (C-terminal) or Histone H3.1 (N-terminal) expression vector, respectively, were fixed in 4% paraformaldehyde for 10 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 15 minutes at room temperature, then blocked with 1% BSA in 10% negative goat serum for 1 hour at room temperature. Cells were then incubated with Mouse anti-Myc tag antibody at 1/1,000 dilution in 1% BSA in PBST overnight at 4 ℃. Goat Anti-Mouse IgG H&L (488) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. Nuclear DNA was labelled in blue with DAPI.
Myc Tag (red) was stained at 1/200 dilution overnight at +4℃. Goat Anti-Rabbit IgG H&L (iFluor™ 594) was used as the secondary antibody at 1/1,000 dilution.
IP
Myc-tag was immunoprecipitated in 2µg C-terminal Myc-tag fusion protein lysate with Mouse anti-Myc tag antibody. Western blot was performed from the immunoprecipitate using Mouse anti-Myc tag antibody at 1/2,000 dilution. Anti-Mouse IgG for IP Nano-secondary antibody at 1:5,000 dilution was used for 60 mins at room temperature.
Lane 1: C-terminal Myc-tag fusion protein lysate (input).
Lane 2: Mouse anti-Myc tag antibody IP in C-terminal Myc-tag fusion protein lysate.
Lane 3: Mouse IgG instead of Mouse anti-Myc tag antibody IP in C-terminal Myc-tag fusion protein lysate.
Blocking/Dilution buffer: 5% NFDM/TBST.
