Western blot analysis was performed on membrane extracts (30 µglysate) of U-87 MG (Lane 1), Neuro-2a (Lane 2), SH-SY5Y (Lane 3), SK-N-AS (Lane 4), and T98G (Lane 5). The blots were probed with Rabbit Anti-SCAMP2 Polyclonal Antibody (Product # PA1-734, 2 µg/ml) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25 µg/ml, 1:4000 dilution). A 36 kDa band corresponding to SCAMP1 was observed across the cell lines and tissues tested. Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 4-12 % Bis-Tris gel (Product # NP0321BOX), XCell SureLock™ Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane with iBlot® 2 Dry Blotting System (Product # IB21001). The membrane was probed with the relevant primary and secondary Antibody following blocking with 5 % skimmed milk. Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

PA1-734 detects secretory carrier membrane protein 2 (SCAMP 2) from mouse testes and AtT20 cell extract as well as Chinese hamster ovary (CHO) cell extract.
PA1-734 has been successfully used in Western blot procedures. By Western blot, this antibody detects an ~38 kDa protein representing SCAMP 2 from CHO cell extract.
PA1-734 immunizing peptide corresponds to amino acid residues 1-17 from human SCAMP 2. This sequence is completely conserved between human and mouse. PA1-734 immunizing peptide (Cat. # PEP-151) is available for use in neutralization and control experiments.
Secretory carrier membrane proteins (SCAMPs) are proteins that are components of post-Golgi membranes. These proteins are implicated to function in membrane trafficking. In fibroblasts, SCAMPs are concentrated in compartments that are involved in the recycling of cell surface receptors and endocytosis. In neurons, SCAMPs are associated with synaptic vesicles, secretion granules and transporter vesicles. SCAMPs are composed of four central transmembrane regions and a cytoplasmic tail. Of the five known SCAMPs, SCAMPs 1-3 contain cytoplasmic N-terminal regions with NPF repeats. NPF repeats are found to interact with EH domain proteins that function in budding of transport vesicles from the plasma membrane or the Golgi complex. SCAMPs 4 and 5 lack the N-terminal NPF repeats. SCAMPs 1-4 are all ubiquitously coexpressed while SCAMP 5 is only detectable in the brain. Studies show that SCAMP 5 is expressed late in development which is coincident with expansion of mature synapses.
