This is a knockout-validated antibody summary, based on the publication "Functional CRISPR screening identifies the ufmylation pathway as a regulator of SQSTM1/p62", as cited below [1]. Labome curates formal publications to compile a list of antibodies with unambiguous specificity within Validated Antibody Database (VAD).

Rabbit monoclonal IgG

Company: Abcam

Antibody: UFSP2

Catalog number: ab185965

Summary: Rabbit monoclonal IgG against a recombinant fragment within human UFSP2 aa 200-400. Reacts with human, mouse, and rat. Suitable for western blot, immunoprecipitation, immunocytochemistry/immunofluorescence, and immunohistochemistry (paraffin).

Western blot

Control and UFSP2-KO H4 neuroglioma cell line (stably expressing Cas9 and GFP-SQSTM1). Cells were lysed in RIPA buffer (Thermo Scientific, Waltham, MA) supplemented with protease inhibitor cocktail (Roche) followed by sonication. Alternatively, protein lysates were prepared in RIPA buffer containing protease inhibitors and 1% SDS followed by purification with QIAshredder columns (Qiagen).

Odyssey blocking buffer for 1 hr or PBS/0.1% Tween-20/5% milk.

Diluted in Odyssey blocking buffer supplemented with 0.1% Tween-20 (Bio-Rad) or in PBS/0.1% Tween-20/5% milk overnight at 4°C.

Anti-rabbit IRDye 800CW (LI-COR) diluted in Odyssey blocking buffer supplemented with 0.1% Tween-20 or anti-rabbit HRP (Thermo Fisher Scientific) diluted in PBS/0.1% Tween-20/5% milk incubated for 1 hr at room temperature.

Odyssey infrared imaging system or SuperSignal West Pico chemiluminescent substrate (Thermo Scientific) and autoradiography.

If the antibody described in this summary is a polyclonal antibody, since polyclonal antibodies are of limited quantity, please inquire the supplier whether any current polyclonal antibody with the same catalog number is exactly the same as the one described in this summary. Sometimes, different bleeds or different animals are used, usually with a different lot number. In such cases, the result in this summary may not apply to the new antibody with the same catalog number.
