Name :
Recombinant Human Cardiotrophin 1 Protein (hFc Tag)
Biological Activity :
Background :
CTF1 is the first HOX11 protein partner identified that plays an important role in hematopoietic precursor cell immortalization. CTF1 was found to protect a gene from silencing when its DNA-binding sites were interposed between the gene and the telomeric extremity, while it did not affect a gene adjacent to the telomere. Protein fusions containing the CTF1 histone-binding domain displayed similar activities, while mutants impaired in their ability to interact with the histone did not. Cardiotrophin-1 (CTF1) has been reported to act as a trophic factor for a few neurons, such as sensory, cholinergic, dopaminergic, motor and cortical neurons. Studies have indicated that CTF1 delays degenerative disease progression in motor neuron disease.
Biological Activity :
Measured in a cell proliferation assay using TF-1 human erythroleukemic cells.The ED50 for this effect is typically 01-0.8 μg/mL.

cardiotrophin 1
Amino Acid Sequence :
Molecular Weight :
The recombinant human CTF1/Fc is a disulfide-linked homodimer. The reduced monomer comprises 460 amino acids and has a predicted molecular mass of 49.5 kDa. The apparent molecular mass of the protein is approximately 54 and 37 kDa in SDS-PAGE under reducing conditions due to glycosylation.
Purity :
> 80 % as determined by SDS-PAGE

Product Concentration :
Storage and Stability :
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Endotoxin Level :
< 1.0 EU per μg of the protein as determined by the LAL method
Protein Construction :
A DNA sequence encoding the human CTF1(NP_001321.1)(Ser2-Ala201) was expressed with the fused Fc region of human IgG1 at the N-terminus.
Buffer Solution :
Lyophilized from sterile PBS, pH 7.4.Please contact us for any concerns or special requirements. Normally 5 % – 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hardcopy of datasheet.
Shipping :
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Redissolution :
A hardcopy of datasheet with reconstitution instructions is sent along with the products. Please refer to it for detailed information.
