Anti-Rat CNTF

E. coli-Derived Recombinant Rat CNTF

This antigen affinity purified polyclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 containing 5.0% w/v trehalose with no calcium, magnesium, or preservatives present.

The lyophilized antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for twelve months from date of receipt. The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. No detectable loss of activity was observed after six months.

IHC (NBF/Par.): This antibody should give satisfactory staining results when used at a concentration of 15 µg/ml. The recommended secondary antibody for IHC is PN:G505. For chromogenic detection with high signal and low background use PN:D100 or PN:K107.
Neutralization: This antibody is useful for neutralization of Rat CNTF bioactivity. The antibody dose required to neutralize 50% (ND₅₀) of the biological activity of Rat CNTF (at 200 ng/ml) is 4 - 8 µg/ml.

Rabbit Anti-Rat Ciliary Neurotrophic Factor (CNTF) recognizes Rat CNTF. This antigen affinity purified polyclonal antibody was purified using a proprietary chromatographic technique that includes covalently immobilizing the antigen proteins or peptides to agarose based beads. This purification method enhances specificity, reduces nonspecific binding of extraneous IgG and provides you with the most reliable reagent available for your early discovery research.

Ciliary neurotrophic factor (CNTF) is a cytokine¹ that supports survival and/or differentiation of a variety of neuronal cell types including sensory, sympathetic, and motoneurons.² With these abilities, CNTF has implications for Parkinson's disease and cell-replacement therapies for other disorders.³ CNTF mimics the biological actions of leptin while overcoming "leptin resistance" and appears to reduce inflammatory signaling cascades associated with lipid accumulation in liver and skeletal muscle. The advantages and disadvantages of CNTF has shown promise as a therapeutic strategy to alleviate obesity-associated diseases.⁴
