Side-by-side comparison of ICC performance using the rabbit polyclonal ab18528 and RabMab® ab125068. Staining was performed on wild-type HeLa cells (top panel) and LAMP2 knockout HeLa cells (bottom panel, available as ab255402). The cells were fixed with 100% methanol (5 min), permeabilized with 0.1% Tween-20 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 ab18528 or ab125068 overnight at +4°C at 3 different concentrations : 1.0 μg/mL, 0.2 μg/mL and 0.04 μg/mL. Secondary antibody incubation was at room temperature for 1h with a goat secondary antibody to Rabbit IgG (Alexa Fluor® 488) (ab150081) (shown in green) at 1/1000 and nuclear DNA was labelled with DAPI (shown in blue). Images were acquired with a high-content analyser (Operetta CLS, Perkin Elmer) and a maximum intensity projection of confocal sections is shown. Some cytoplasmic cross-reactivity is seen using ab18528 at 1.0 μg/mL, but further titration of the antibody improves the ICC staining result. The RabMab® ab125068 shows negligible non-specific staining across the dilution range. Quantification of the antibody signal was performed using a minimum of 180 cells and data are presented as mean ± SD.Optimal dilutions/concentrations may vary across different cell types/experiment conditions and should be determined by the end user.

ab125068 staining LAMP2a in wild-type HeLa cells (top panel) and LAMP2 knockout HeLa cells (bottom panel, available as ab255402). The cells were fixed with 4% formaldehyde (10min), permeabilized with 0.1% Tween-20 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 ab125068 at 0.04 μg/mL and ab7291 at 1 μg/mL 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) (shown in green) and goat secondary antibody to Mouse IgG (Alexa Fluor^® 594) (ab150120) (shown in red) both at 1/1000. Nuclear DNA was labelled with DAPI (shown in blue).

In our hands, permeabilization with 0.1% Triton X-100 (5 min) resulted in greatly reduced signal and we recommend using 0.1% Tween-20 (5 min) for detecting this target.

Western blot - Anti-LAMP2A antibody [EPR4207(2)] - Lysosome Marker (AB125068)

False colour image of Western blot : Anti-LAMP2A antibody [EPR4207(2)] - Lysosome Marker staining at 1/2000 dilution, shown in green; Mouse anti-Alpha Tubulin [DM1A] (ab7291) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab125068 was shown to bind specifically to LAMP2A. A band was observed at 100 kDa in wild-type HeLa cell lysates with no signal observed at this size in LAMP2 CRISPR-Cas9 edited cell line ab255402 (CRISPR-Cas9 edited cell lysate ab263861). The band observed in the CRISPR-Cas9 edited lysate lane below 100 kDa is likely to represent a truncated form of LAMP2A. This has not been investigated further and the functional properties of the gene product have not been determined. To generate this image, wild-type and LAMP2 CRISPR-Cas9 edited HeLa cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

Blocking and diluting buffer and concentration : 5% NFDM /TBST. ab181602 was used as a GAPDH loading control. LAMP2A is highly expressed in placenta, lung and liver, less in kidney and pancreas, low in brain and skeletal muscle (PMID : 10212251PubMed : 7488019, PubMed : 26856698). For better using it in tissue with low expression level, we suggest optimizing experimental protocols (increasing lysate amount, using lower dilution or higher sensitivity ECL substrate).

This blot was produced using 4-20% SDS-PAGE containing 15 μg of mouse kidney lysate per lane at 150V for 1hr before being transferred onto a 0.45 μm PVDF membrane at 75V for 1hr. The membrane was then blocked for 1hr using 5% NFDM/TBST, then incubated with ab125068 (1/1000) at room temperature for 1hr. After being washed three times in TBST, the membrane was incubated with Peroxidase conjugated goat anti-rabbit IgG (H+L) (ab97051) at 1/20,000 dilution for 1hr at room temperature. The membrane was washed three times again. Then the signal was developed using the ECL technique. ab125068 was stored at a range of temperatures (+4°C, +22°C, +37°C) for 1 week before being tested in WB. The image shows the band intensity remains relatively constant for temperatures ranging between 4°C, 22°C and 37°C, demonstrating that antibody activity is not affected under these conditions.
