Recombinant Anti-KDM1/LSD1 antibody [EPR6825] - BSA and Azide free (ab224270)

ChIC/CUT&RUN was performed using a pAG-MNAse at a final concentration of 700 ng/µL. 2.5X10^5 of Human wild-type HeLa cell line (ab255928) or KDM1A (LSD1) knockout HeLa cell line (ab265790) were used along with 5µg of ab129195 [EPR6825]. Assay Quality Control was conducted using 5µg Anti-CTCF(ab188408) on the same cell lines. The resulting DNA was sequenced on the Illumina NovaSeq 6000 to a depth of 10 million reads.  The negative IgG control ab172730 is also shown.

  Lanes 1- 2: Merged signal (red and green). Green - ab129195 observed at 110 kDa. Red - Anti-GAPDH antibody [6C5] - Loading Control (ab8245) observed at 37 kDa.

 ab129195 was shown to react with KDM1/LSD1 in wild-type HeLa cells in western blot. Loss of signal was observed when knockout cell line ab265790 (knockout cell lysate ab256965) was used. Wild-type HeLa and KDM1 knockout HeLa cell lysates were subjected to SDS-PAGE. Membrane was blocked for 1 hour at room temperature in 0.1% TBST with 3% non-fat dried milk. ab129195 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) overnight at 4°C at a 1 in 1000 dilution and a 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^®800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^®680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

Chromatin was prepared from HCT 116 cells according to the Abcam X-ChIP protocol. Cells were fixed with 1% formaldehyde for 10 minutes. The ChIP was performed with 25µg of chromatin, 5µg of ab129195 (red), and 20µl of protein A/G sepharose beads slurry (10µl of sepharose A beads + 10µl of sepharose G beads). 5μg of rabbit normal IgG was added to the beads control (grey). The immunoprecipitated DNA was quantified by real time PCR (Sybr green approach).

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab129195).

This ICC data was generated using the same anti-KDM1/LSD! antibody clone [EPR6825] in a different buffer formulation (cat# ab129195).

ab129195 staining KDM1A/LSD1 in wild-type HAP1 cells (top panel) and KDM1A knockout HAP1 cells (bottom panel). The cells were fixed with 4% formaldehyde (10min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab129195 at 1μg/ml concentration and ab195889 at 1/250 dilution (shown in pseudo colour red) overnight at +4°C, followed by a further incubation at room temperature for 1h with a goat secondary antibody to Rabbit IgG (Alexa Fluor® 488) (ab150081) at 2 μg/ml (shown in green). Nuclear DNA was labelled in blue with DAPI.

Lanes 1 - 4: Merged signal (red and green). Green - ab129195 observed at 110 kDa. Red - loading control, ab8245, observed at 37 kDa.

ab129195 was shown to specifically react with KMD1 / LSD1 in wild-type HAP1 cells. No band was observed when KMD1 / LSD1 knockout samples were used. Wild-type and KMD1 / LSD1 knockout samples were subjected to SDS-PAGE. ab129195 and ab8245 (loading control to GAPDH) were both diluted 1/10,000 and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10,000 dilution for 1 hour at room temperature before imaging.

Immunofluorescence staining of HeLa cells with purified ab129195 at a working dilution of 1/100, counter-stained with DAPI. The secondary antibody was Alexa Fluor^® 488 goat anti-rabbit (ab150077), used at a dilution of 1/1000. ab7291, a mouse anti-tubulin antibody (1/1000), was used to stain tubulin along with ab150120 (Alexa Fluor^® 594 goat anti-mouse, 1/1000), shown in the top right hand panel. The cells were fixed in 4% PFA and permeabilized using 0.1% Triton X 100. The negative controls are shown in bottom middle and right hand panels - for negative control 1, purified ab129195 was used at a dilution of 1/500 followed by an Alexa Fluor^® 594 goat anti-mouse antibody (ab150120) at a dilution of 1/500. For negative control 2, ab7291 (mouse anti-tubulin) was used at a dilution of 1/500 followed by an Alexa Fluor^® 488 goat anti-rabbit antibody (ab150077) at a dilution of 1/400.
