Phosphate-buffered (10 mM) isotonic (0.9%, w/v) saline (“PBS, " pH 7.2) with sodium azide (0.02%, w/v) added as a preservative.

Three antipeptide antibodies were generated in chickens against sequences shared between the mouse (P08551) and human (P07196) gene products. Antibodies were affinity-purified and mixed in equal concentrations. These antibodies have been validated with human, mouse and rat tissues.

Human Neurofilament Light Chain (NFL) is a 61, 516 dalton protein (543 amino acids) expressed in the axons of CNS and PNS neurons, where it plays a role in maintaining the structural integrity of the axon. Mutations of the NFL gene product are responsible for some forms of autosomal dominant Charcot-Marie-Tooth neuropathies in humans (i.e., CMT type 1F).

Synthetic peptides

Affinity-Purified IgY

Yes

Chickens were immunized with three synthetic peptide / keyhole limpet hemocyanin (KLH) conjugates. These synthetic peptides corresponded to different regions of the NF-L gene product, but are shared between the human (P07196, NCBI) and mouse (P08551, NCBI) protein sequences. After repeated injections, immune eggs were collected, and the IgY fractions were purified from the yolks. These IgY fractions were then affinity-purified using a peptide column, and the concentrations of the eluates adjusted to 300 µg/mL. Finally, equal volumes of each of the three affinity purified anti-peptide antibodies were mixed, and the preparation was filter-sterilized.
