Detection of Human Syntaxin 5 antibody by Western Blot.

Detection of Human Syntaxin 5 by Western Blot.

Western blot shows lysates of T47D human breast cancer cell line and Raji human Burkitt's lymphoma cell line. PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human/Rat Syntaxin 5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5687) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). Specific bands were detected for Syntaxin 5 at approximately 35 and 42 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Syntaxin 5 antibody in SH-SY5Y Human Cell Line by Immunocytochemistry (ICC).

Syntaxin 5 in SH-SY5Y Human Cell Line.

Syntaxin 5 was detected in immersion fixed SH-SY5Y human neuroblastoma cell line using Goat Anti-Human/Rat Syntaxin 5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5687) at 1.7 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Syntaxin 5 antibody in Human Brain by Immunohistochemistry (IHC-P).

Syntaxin 5 in Human Brain.

Syntaxin 5 was detected in immersion fixed paraffin-embedded sections of human brain (substantia nigra) using Goat Anti-Human/Rat Syntaxin 5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5687) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in neurons. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Syntaxin 5 antibody in Rat Brain by Immunohistochemistry (IHC-Fr).

Syntaxin 5 in Rat Brain.

Syntaxin 5 was detected in immersion fixed frozen sections of rat brain using Goat Anti-Human/Rat Syntaxin 5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5687) at 3 µg/mL overnight at 4 °C. Tissue was stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to neuronal cytoplasm. View our protocol for Fluorescent IHC Staining of Frozen Tissue Sections.

Detection of Human Syntaxin 5 antibody by Simple WesternTM.

Detection of Human Syntaxin 5 by Simple WesternTM.

Simple Western lane view shows lysates of T47D human breast cancer cell line and Raji human Burkitt's lymphoma cell line, loaded at 0.2 mg/mL. Specific bands were detected for Syntaxin 5 at approximately 39 and 47 kDa (as indicated) using 25 µg/mL of Goat Anti-Human/Rat Syntaxin 5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5687) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: Syntaxin 5

Syntaxin 5 (STX5) is a predicted 41‑42 kDa member of the syntaxin family of proteins. It is a t‑SNARE that is widely expressed (but not in striated muscle), and embedded in either the cis‑Golgi network (a 37 kDa form) or the ER (the 46 kDa form). STX5 is involved in the regeneration and maintenance of the Golgi apparatus after mitosis. Human STX5 is a type IV single‑pass transmembrane protein (very long cytoplasmic N‑terminus) that is 355 amino acids (aa) in length. It contains an ER retrieval signal (Arg4Lys5Arg6), a t‑SNARE domain (aa 263‑325) with a coiled‑coil region (aa 287‑318), and a C‑terminal transmembrane sequence. The 35 kDa short form exhibits an alternate start site at Met55. Two other potential splice variants show either the Met55, or a Met97 start site coupled to a 19 aa substitution for aa 303‑355. Over aa 55‑300, human STX5 shares 94% aa identity with mouse STX5.
