- 状态
- Lyophilized
- 溶解方式
- Rat CNTF should be reconstituted in PBS to a concentration of 0.1 mg/mL. This solution can be diluted in water or other buffered solutions.
- 缓冲液
- 5 mM sodium acetate, pH 6.5
- 储存条件
- RT,-20 °C
- 储存方法
- The lyophilized powder although stable at room temperature for 3 weeks, is best stored desiccated at -20°C. Reconstituted rat CNTF should be stored in working aliquots at -20°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).

- 背景
-
Ciliary neurotrophic factor (CNTF) is a polypeptide initially purified from chick embryo ocular tissue and identified as a trophic factor for embryonic chick ciliary parasympathetic neurons in culture. Subsequent studies have demonstrated that CNTF is a survival factor for additional neuronal cell types including: primary sensory neurons, motor neurons, basal forebrain neurons and type 2 astrocytes. CNTF has also been shown to prevent the degeneration of motor axons after axotomy. The cDNA for CNTF encodes a 200 amino acid residue polypeptide that lacks a signal sequence. CNTF is highly conserved across species and exhibits cross-species activities. Human and rat CNTF share approximately 83% homology in their protein sequence. CNTF is structurally related to IL6, IL11, LIF, and OSM. All of these four helix bundle cytokines share gp130 as a signal-transducing subunit in their receptor complexes. The cDNA for recombinant rat CNTF (Ala2–Met200) was cloned from total RNA of a rat embryo using standard protocols. Ciliary Neurotrophic Factor (CNTF) is a potent neural factor that was originally characterized as a survivability factor for chick ciliary neurons in vitro. More recently, CNTF has been shown to promote survivability and differentiation of other neuronal cell types. Rat CNTF is a 22.7 kDa protein containing 199 amino acid residues.
