Immunocytochemistry/ Immunofluorescence - Anti-Munc18-1 antibody [EPR4850] - BSA and Azide free (AB248059)

This data was developed using ab124920, the same antibody clone in a different buffer formulation.

ab124920 was shown to react with STXBP1 in wild-type U-87 MG cells in immunocytochemistry with loss of signal observed in STXBP1 knockout cell line ab322392. Wild-type and knockout cells were mixed and pelleted at a 1 : 1 ratio on coverslips. The cells were fixed with 4% paraformaldehyde (15 min) then permeabilized with 0.1% Triton X-100 (10min) and then blocked with 1x PBS, 0.01% Triton X-100, 5% BSA, 5% NGS. The cells were then incubated with ab124920 at 1/100 dilution overnight at 4°C followed by a further incubation at room temperature for 1h with a goat anti-rabbit secondary antibody to (Alexa Fluor® 555) at 0.5 µg/ml. Acquisition of the green (wild-type), red (antibody staining) and far-red (knockout) channels was performed. Representative grayscale images of the red channel are shown. Wild-type and knockout cells are outlined with yellow and magenta dashed line, respectively. Schematic representation of the mosaic strategy used is shown on the bottom-right panel. Image was acquired with a Zeiss(LSM-880).

Immunoprecipitation - Anti-Munc18-1 antibody [EPR4850] - BSA and Azide free (AB248059)

This data was developed using ab124920, the same antibody clone in a different buffer formulation.

Immunoprecipitation of STXBP1 in U-87 MG cells. Lysates were prepared and immunoprecipitation was performed using 2 µg of ab124920 pre-coupled to Protein A beads. Samples were then washed and processed for western blot.

Western blot - Anti-Munc18-1 antibody [EPR4850] - BSA and Azide free (AB248059)

This data was developed using ab124920, the same antibody clone in a different buffer formulation.

ab124920 was shown to react with STXBP1 in wild-type U-87 MG cells in Western blot with loss of signal observed in STXBP1 knockout cell line ab322392. Wild-type U-87 MG and STXBP1 knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 5% milk in TBST for 1 hr before incubation with ab124920 overnight at 4 °C at a 1/10000 dilution. Blots were incubated with secondary antibodies at 0.2 µg/mL before imaging.
