25x Biotin-detection Ab(human CNTF Biotin-dAb). PN: B111365B. One vial containing 100 µL of biotinylated anti-human CNTF.

Lyophilized Standard Mix-Human Group 10, Panel A, 9-Plex. PN: HG1009A. One vial containing lyophilized recombinant BTC, CNTF, FGF-4, Follistatin, IL-19, KGF, PDGF-AA, PDGF-BB, and PIGF-1.  Note: If multiple analyte kits on the above target list are ordered as a panel, only one vial of standard mix is supplied for those analyte kits.

Application: Optimal antibody pair and antigen standard for assaying human Human CNTF. Can be multiplexed with other analytes in Human Group 10.  To be used in conjunction with the AimPlex NR Basic Kit (PN: P100001) and a diluent kit. Refer to the AimPlex Multiplex Immunoassay User Manual and kit inserts for the assay procedure.

Storage:  2-8 C in the dark.

Important: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Description:

Ciliary neurotrophic factor (CNTF) is a polypeptide hormone and nerve growth factor whose actions have mainly been studied in the nervous system where it promotes neurotransmitter synthesis and neurite outgrowth in certain neural populations including astrocytes. The protein is a potent survival factor for neurons and oligodendrocytes and may be relevant in reducing tissue destruction during inflammatory attacks. A mutation in this gene, which results in aberrant splicing, leads to ciliary neurotrophic factor deficiency, but this phenotype is not causally related to neurologic disease. In addition to the predominant monocistronic transcript originating from this locus, the gene is also co-transcribed with the upstream ZFP91 gene. Co-transcription from the two loci results in a transcript that contains a complete coding region for the zinc finger protein but lacks a complete coding region for ciliary neurotrophic factor. CNTF has also been shown to be expressed by cells on the bone surface, and to reduce the activity of bone forming cells, osteoblasts.
