Flow Cytometry (Intracellular) - Anti-LINE-1 ORF1p antibody [EPR21844-108] - BSA and Azide free (AB245122)

This data was developed using the same antibody clone in a different buffer formulation (ab216324).

Flow cytometry overlay histogram showing left F9 positive cells and right negative NIH3T3 stained with ab216324 (red line). The cells were fixed with 4% formaldehyde (10 min) and then permeabilised with 0.1% PBS-Triton X-100 for 15 mins. The cells were then incubated in 1x PBS containing 10% normal goat serum to block non-specific protein-protein interaction followed by the antibody (ab216324) (1x 10⁶ in 100μl at 1.0μg/ml (1/1980 dilution)) for 30 mins at 22°C.

The secondary antibody Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) preadsorbed was incubated at 1/4000 dilution for 30 mins at 22°C

Isotype control antibody (black line) was Recombinant Rabbit IgG, monoclonal [EPR25A] - Isotype Control (ab172730) used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control.

Acquisition of >5000 events were collected using a 50 mW Blue laser (488nm) and 525/40 bandpass filter.

This antibody gave a positive signal in F9 Fixed with 80% methanol (5 mins) / permeabilised with 0.1% PBS-Triton X-100 for 15 minss under the same conditions.

ab216324 staining LINE-1 ORF1p in Wt and Maelstrom (Mael) null mutant mouse testis by Immunohistochemistry (Frozen sections). Mael is a repressor of LINE-1 transposable elements, so the expression of LINE-1 ORF1p increases in this KO. Tissue was fixed with paraformaldehyde and blocked with 10% serum for 30 minutes at 25°C; Samples were incubated with primary antibody (1/100, 1/500 and 1/1000) for 12 hours at 4°C in 3% Donkey Serum in PBS + 0.05% Triton X. Donkey Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150073) (1/1000) was used as the secondary antibody.
