Western blot analysis of Cysteine String Protein alpha was performed using whole cell lysates of SH-SY5Y (Lane 1) and NIH/3T3 (Lane 2). The blots were probed with Anti- Cysteine String Protein alpha Rabbit polyclonal Antibody (Product # PA1-776, 2 µg/ml) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.4 µg/ml, 1:2500 dilution). Bands of ~ 35 and 26 kDa, corresponding to mature and immature forms of Cysteine String Protein alpha respectively, were observed across cell lines 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 using iBind™ Flex Western Starter Kit (Product # SLF2000S). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

PA1-776 detects Cysteine String Protein Alpha in mouse and rat brain samples.
PA1-776 has been successfully used in Western blot procedures. By Western blot, this antibody detects a ~34 kDa protein representing Cysteine String Protein Alpha in rat and mouse brain homogenates.
The PA1-776 immunogen is a synthetic peptide corresponding to residues E(180) T T Q L T A D S H P S Y H T D G F N(198) of rat CSP. This sequence is conserved across many species including mouse, human and bovine. This peptide (Cat. # PEP-287) is available for use in neutralization and control experiments.
Cysteine string protein alpha (CSPalpha) is a synaptic vesicle protein that contains a DNA-J domain characteristic of Hsp40 chaperones. Cysteine-string proteins are membrane-bound proteins associated primarily with nerve endings and synaptic vesicles in the brain. These proteins play an important role in presynaptic function and may be involved in calcium-dependent neurotransmitter release. CSP proteins may act as presynaptic chaperones that assist in maintaining synaptic function.
