|A DNA sequence encoding the human CKB (P12277)(Pro2-Lys381) was fused with a polyhistide tag at the N-terminus.|
|Kinases are highly recommended to be shipped at frozen temperature with blue ice or dry ice.|
Shipment made at ambient temperature may seriously affect the activity of the ordered products.
|> 90 % as determined by SDS-PAGE|
|Kinase activity untested|
|< 1.0 EU per μg of the protein as determined by the LAL method|
|Samples are stable for up to twelve months from date of receipt at -70℃|
|The recombinant human CKB consists of 398 amino acids and has a calculated molecular mass of 44.8 kDa. The recombinant protein migrates as an approximately 45 kDa band in SDS-PAGE under reducing conditions.|
|Lyophilized from sterile 50mM Tris, 100mM NaCl, 10% gly, pH 8.0.|
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
|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.|
|A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.|
CKB(Creatine kinase B type) contains 1 phosphagen kinase C-terminal domain and 1 phosphagen kinase N-terminal domain. It belongs to the ATP:guanido phosphotransferase family. CKB consists of a homodimer of two identical brain-type CK-B subunits. CKB is a cytoplasmic enzyme involved in cellular energy homeostasis, with certain fractions of the enzyme being bound to cell membranes, ATPases, and a variety of ATP-requiring enzymes in the cell. There, CKB forms tightly coupled microcompartments for in situ regeneration of ATP that has been used up. CKB reversibly catalyzes the transfer of "energy-rich" phosphate between ATP and creatine or between phospho-creatine (PCr) and ADP. Its functional entity is a homodimer in brain, smooth muscle as well as in other tissues and cells such as neuronal cells, retina, kidney, bone etc.
