The cells were fixed in 4% formaldehyde and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L). Immunofluorescence staining of A549 cell with 5% goat serum, counter-stained with DAPI.

IHC image of CSB-PA836235LA01HU diluted at 1:300 and staining in paraffin-embedded human prostate cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.05% DAB. Secondary antibody only control: uses 1% BSA instead of primary antibody

Description

The recombinant peptide corresponding to amino acids 263-490 of the human VPS39 is used as the immunogen to immunize the rabbit to yield the anti-VPS39 antibody. The VPS39 polyclonal antibody exists as an unconjugated IgG isoform. Its purity is 95%⁺ using protein G purified. It reacts with human and mouse VPS39. This VPS39 antibody has been validated for use in ELISA, WB, IF, and IHC analyses.

VPS39 mainly regulates endosomal membrane trafficking and fusion. It is a subunit of the homotypic fusion and protein sorting (HOPS) complex, which is involved in the tethering and fusion of endosomes and lysosomes. It is also involved in the regulation of lysosomal biogenesis, autophagy, and signaling pathways. Mutations in the VPS39 gene have been linked to various diseases such as Hermansky-Pudlak syndrome.

Target Background

Function

Regulator of TGF-beta/activin signaling, inhibiting SMAD3- and activating SMAD2-dependent transcription. Acts by interfering with SMAD3/SMAD4 complex formation, this would lead to inhibition of SMAD3-dependent transcription and relieve SMAD3 inhibition of SMAD2-dependent promoters, thus increasing SMAD2-dependent transcription. Does not affect TGF-beta-induced SMAD2 or SMAD3 phosphorylation, nor SMAD2/SMAD4 complex formation.; Plays a role in vesicle-mediated protein trafficking to lysosomal compartments including the endocytic membrane transport and autophagic pathways. Acts as a component of the putative HOPS endosomal tethering complex which is proposed to be involved in the Rab5-to-Rab7 endosome conversion probably implicating MON1A/B, and via binding SNAREs and SNARE complexes to mediate tethering and docking events during SNARE-mediated membrane fusion. The HOPS complex is proposed to be recruited to Rab7 on the late endosomal membrane and to regulate late endocytic, phagocytic and autophagic traffic towards lysosomes. Involved in homotypic vesicle fusions between late endosomes and in heterotypic fusions between late endosomes and lysosomes. Required for fusion of endosomes and autophagosomes with lysosomes.
