Synaptic Systems - Neurexin1/2/3

Cat. No.: 175 003

Amount: 50 µg

Price: $380.00

Cat. No. 175 003	50 µg specific antibody, lyophilized. Affinity purified with the immunogen. Albumin and azide were added for stabilization. For reconstitution add 50 µl H₂O to get a 1mg/ml solution in PBS. Then aliquot and store at -20°C to -80°C until use. Antibodies should be stored at +4°C when still lyophilized. Do not freeze!
Applications	WB: 1 : 500 up to 1 : 1000 (AP staining) (see remarks) gallery IP: not tested yet ICC: not recommended IHC: not tested yet IHC-P: not tested yet
Immunogen	Recombinant protein corresponding to AA 1459 to 1514 and 1657 to 1712 and 1524 to 1578 from rat Neurexin1/2/3
Reactivity	Reacts with: rat (Q63372, Q63376, Q07310), mouse (Q9CS84, E9PUM9, Q8C985). Other species not tested yet.
Specificity	Due to the homology of the cytoplasmic tails of α- and β-neurexins 1, 2 and 3, this antiserum detects all isoforms and their corresponding splice-variants. K.O. validated PubMed: 30104341
Remarks	WB: Non-boiled samples yield stronger signals.

Background

α- and β-neurexins are single pass transmembrane proteins with a short cytoplasmic C-terminus and a long extracellular N-terminal part. In α-neurexins the extracellular sequence is substantially longer than in β-neurexins. Alternative splicing of the N-terminal part even confers more complexity to this protein family suggesting distinct binding partners for the extracellular regions. In contrast, the C-termini are highly conserved in the different isoforms and splice-variants and they share overlapping cytosolic binding partners.
Neurexins are receptor like molecules that form heterologous cell contacts with post-synaptic cell surface proteins at synaptic connections (e.g. β-neurexins with neuroligins). They also serve as receptors for the black widow toxin α-latrotoxin which induces neurotransmitter release.
