Snap-8 (10mg)

Description

Product: Snap-8 (10mg) Product Overview: Snap-8 is a synthetic octapeptide analog derived from the N-terminal domain of SNAP-25, a 206-amino-acid protein that forms part of the SNARE (Soluble N-ethylmaleimide-sensitive factor Attachment protein REceptor) complex. SNAP-25 is essential for synaptic vesicle docking and membrane fusion processes in neuronal and non-neuronal cell types. Snap-8 has been designed to investigate the modulation of SNARE complex assembly and its downstream effects on vesicular exocytosis. Supplied as a lyophilized powder, this peptide serves as a research tool for studying SNARE-mediated membrane fusion, neurotransmitter release dynamics, and protein-protein interactions within the exocytotic machinery. Research Profile: Snap-8 has been investigated in preclinical models for its biochemical interactions with components of the vesicle fusion apparatus and downstream cellular effects. - SNARE complex modulation: Studied for its capacity to compete with endogenous SNAP-25 for incorporation into the ternary SNARE complex (SNAP-25/syntaxin-1/VAMP-2), assessed through co-immunoprecipitation and native PAGE gel-shift assays. - Vesicular exocytosis: Examined for its effects on calcium-dependent exocytotic vesicle fusion in neuroendocrine cell models (PC12 cells) using amperometric measurements and capacitance recordings. - Neurotransmitter release dynamics: Investigated for its influence on catecholamine and acetylcholine release from synaptic terminals in ex vivo nerve-muscle preparations and primary neuronal cultures. - Protein-protein interaction mapping: Explored using fluorescence resonance energy transfer (FRET) and surface plasmon resonance (SPR) to characterize binding kinetics between Snap-8 and SNARE complex components. - Keratinocyte biology: Studied in skin cell culture models for its effects on calcium-mediated exocytotic processes and lamellar body secretion in epidermal keratinocytes. - Secretory pathway research: Investigated for its effects on regulated secretory pathways in mast cell degranulation models and chromaffin cell exocytosis assays. - Peptide stability profiling: Examined for its resistance to enzymatic degradation by DPP-IV and other serum proteases, with half-life characterization in biological matrices. Key Research Applications: Snap-8 is utilized across neuroscience, cell biology, and dermatological research as a SNARE-targeted peptide. - SNARE complex biochemistry: Applied in reconstituted liposome fusion assays and in vitro binding studies to dissect SNARE-mediated membrane fusion mechanisms. - Neurosecretion models: Used in electrophysiological and biochemical studies of neurotransmitter release and synaptic vesicle cycling. - Dermatological research: Investigated in skin biology models for its effects on keratinocyte secretory function and epidermal barrier processes. - Exocytosis pathway dissection: Employed as a competitive inhibitor tool to probe the functional contributions of individual SNARE components. - Peptide pharmacology: Studied for its structure-activity relationships relative to other SNAP-25-derived peptide fragments in comparative SNARE inhibition assays.
