General Notes
This product (Catalog No. CABT-BL3604) is a rabbit-derived polyclonal antibody raised against human TMEM139, targeting the amino acid region 26–216 of the protein. This antibody exhibits cross-reactivity with Human TMEM139 from mouse. It has been affinity purified by Protein A. TMEM139 (Transmembrane Protein 139) is a multi-pass transmembrane protein with limited functional characterization in current biological literature. It is predicted to localize to cellular membranes, where it may participate in membrane-associated processes such as transport, signaling, or organization of protein complexes. Like many TMEM family members, TMEM139 lacks well-defined enzymatic domains, suggesting a role as a structural or regulatory component rather than a catalytic enzyme. Expression profiling indicates variable tissue distribution, but no strong tissue-specific function has been established. At present, its physiological roles, interacting partners, and signaling pathways remain largely unknown, and functional insights are primarily derived from bioinformatic predictions and sequence conservation analyses. Overall, TMEM139 is considered an uncharacterized membrane protein awaiting further experimental validation.
CABT-BL3604 is suitable for use in Western blot (WB) (1:500–1:1,000), IHC (1:20–1:200) applications.
CABT-BL3604 is supplied as a liquid formulation in PBS with 0.02% sodium azide and 50% glycerol, pH 7.3. For long-term storage, keep at −20 °C. For short-term use, store at 2–8 °C. Avoid repeated freeze–thaw cycles to maintain antibody integrity and performance.
