Immunofluorescence analysis of Syntaxin 1 was performed using 70% confluent log phase SH-SY5Y cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 2% BSA for 1 hour at room temperature. The cells were labeled with Syntaxin-1 Rabbit Polyclonal Antibody (PA11042) at 2ug/ml in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (A27034) a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing cytoplasmic localization. Panel e shows the no primary antibody control. The images were captured at 60X magnification.

PA1-1042 detects Syntaxin 1 in rat, mouse and bovine samples.
PA1-1042 has been successfully used in Western blot procedures. By Western blot, this antibody detects a ~33 kDa protein representing Syntaxin 1 in rat, mouse and bovine brain tissue samples.
The PA1-1042 immunogen is a synthetic peptide corresponding to residues V(22) T V D R D R F M D E F F E Q V E E I R(41) of rat Syntaxin 1. This sequence is conserved in mouse, human and bovine. The PA1-1042 immunizing peptide (Cat. # PEP-278) is available for use in neutralization and control experiments.
Syntaxin 1 is a small integral membrane protein that is abundantly expressed in neurons and neuroendocrine cells and thought to be implicated in the regulation of synaptic neurotransmitter release.
Syntaxin 1 interacts with several other proteins important for synaptic function (SNAP 25, Munc 18). Syntaxin 1 is the main target of one of the Botulinum neurotoxins (BoNT/C1) which, however, cannot cleave the protein when complexed with its partner proteins in the fusion complex.
Syntaxin 1 is an essential component of the neurotransmitter release machinery, and regulation of Syntaxin 1 expression levels is thought to contribute to the mechanism underlying learning and memory.
