Background Information
Barkor, also named as KIAA0831, Atg14 and Atg14L, is required for both basal and inducible autophagy. It plays a role in autophagosome formation and MAP1LC3/LC3 conjugation to phosphatidylethanolamine. Barkor promotes BECN1 translocation from the trans-Golgi network to autophagosomes. This antibody is specific to KIAA0831(Barkor).

Reviews
What customers say
Most reviewers report positive experiences. Two users rated it 5 stars, highlighting its ease of use and strong performance in Western Blot, IHC, and IF at dilutions of 1:400–1:1000. One user gave 1 star, noting that in U2OS cells the IF staining showed an unexpected perinuclear accumulation rather than the expected diffuse or punctate ATG14 pattern. Overall, the antibody is well-received for general applications, though one case suggests potential specificity concerns in certain cell lines for immunofluorescence.

Mounika (Verified Customer) (03-24-2026) | Very good antibody, happy to have it our projects!
|
Mounika (Verified Customer) (01-08-2026) | Very wonderful antibodies, easy to work with! good for western blots
|
Charlotte (Verified Customer) (01-25-2018) | I do not think that this antibody works properly in U2OS cells. According to the litterature ATG14 is supposed to have a diffuse or punctae pattern and not this huge accumulation near the nucleus.
