  ANTIBODIES  

(anti-Human and others as indicated)

RDI Division of Fitzgerald Industries Intl  offers a wide line of  antibodies. Since no one antibody works best for all applications (neutralization, blotting, ELISA, etc), we offer many different types of antibodies to help solve this problem. Please inquire for other applications or types of antibodies not listed below.

Mouse anti-Acetylcholine Receptor Alpha Monoclonal

cat# RDI-ACHERA1abm      $438.00/vial 50ug

       RDI-ACHERA1abm-1   $750.00/vial 150ug

Background: Acetylcholine is an amine neurotransmitter at the neuromuscular   junction. It is released from the presynaptic membrane of a   cholinergic synapse into the synaptic cleft. It   diffuses across the cleft and binds acetylcholine receptors (AChR)   on the postsynaptic membrane. Receptor binding induces   postsynaptic membrane depolarization and the generation of an action potential that produces effects such as muscle contraction. The AChR is a 250kDa pentameric complex of four transmembrane subunits in a stoichiometry of a2bgd. In response to ligand binding, all subunits participate in the formation of an integral cation channel. However, the acetylcholine binding site is primarily within the a subunit. Myasthenia gravis (MG) is an autoimmune condition in which AchR levels are decreased. Autoantibodies bind and crosslink the AchRs leading to their internalization and degradation. This results in a decreased number of functional AChRs. Patients develop muscular weakness and some voluntary muscle fatigue. However, development of MG is also affected by genetic factors. One of the allelic forms of the AChRa gene appears to significantly contribute to MG susceptibility.

Mouse anti-Acetylcholine Receptor BETA Monoclonal

cat#  RDI-ACHERBabm        $438.00/vial 50ug

        RDI-ACHERBabm-1     $750.00/vial 150ug

Background: The AChR is a 250kDa pentameric complex of four honologous trans membrane subunits in a stoichiometry of alpha beta gamma delta. Agrin is a protein that mediates nerve-inducing AChR aggregation at developing neuromuscular junctions. It has been shown that agrin induces phosphorylation of the beta, gamma, and delta subunits of AChRs in cultured myotubes. The Beta subunit is tyrosine phosphorylated while the gamma and delta subunits appear to be serine/threonine phosphorylated. The agrin-induced phosphorylation generally precedes receptor aggregation and inhibition of agrin-induced AChR aggregation and is also known to inhibit tyrosine phosphorylation of the B subunit. Thus agrin-induced tyrosine phosphorylation of the AChRB subunit appears to play a critical role in AChR aggregation. In addition, phosphorylation of the  AChR by tyrosine kinases has been correlated with a modulation of   the rapid rate of receptor desensitizaion and may play a role in the nerve-induced clustering of the AChR at the synapse. Two Src family protein tyrosine kinases, fyn, and Fyk, appear to be involved in the regulation of synaptic transmission at the neuromuscular junction by phosphorylating the AChR. The data suggest that fyn and Fyk can phosphorylate the AChR. The data suggest that fyn and Fyk can phosphorylate the AChR delta subunit and subsequently bind to delta through their SH2 domains. The B subunit induced tyrosine phosphorylation may proceed through a different set of protein tyrosine kinases.
