Ni Sepharose excel media

GE Healthcare

Ni Sepharose excel media

His Mag- and Ni Sepharose excel are immobilized metal ion affinity chromatography (IMAC) media (resins) designed for capture and purification of histidine-tagged proteins secreted into eukaryotic cell culture supernatants.

Nickel ions are very strongly bound to both media, enabling direct loading of large sample volumes without removing agents that normally would cause metal ion stripping. Both media significantly simplify and speed up the workflow and are excellent choices when working with purification of histidine-tagged proteins secreted from eukaryotic cells. 

Key features:

  • Load eukaryotic cell culture samples containing secreted histidine-tagged proteins directly with retained binding capacity
  • Increase target protein yield and decrease degradation through reduced and simplified sample handling
  • Choose between several different formats for screening and preparative purification of histidine-tagged proteins 


IMAC purification of histidine-tagged proteins secreted into eukaryotic cell culture supernatants has traditionally been challenging because of incompatibility between the IMAC medium and the cell culture medium. The cell culture medium strips the immobilized metal ions from the IMAC medium during sample loading, resulting in low or no binding of the target protein. The purification has been further complicated by the fact that the target protein concentration is often low. This requires the use of large sample volumes, which in turn might lead to increased metal ion stripping. Considerable sample pretreatment has been required to overcome these problems, an example being buffer exchange by diafiltration in combination with concentration procedures. Such pretreatment is time consuming, potentially harmful to sensitive proteins, and can cause unnecessary loss of target protein.

PromoKine’s plant-derived cytokines and growth factors are free of animal components, serum traces, and antibiotics.


Growing importance of fields like stem cell research require cytokines and growth factors produced in a safe host organism that prevent the occurrence of unwanted cellular responses caused by high endotoxin levels and other bacterial or mammalian impurities. Many commercially available cytokines and growth factors have endotoxin levels and other impurities high enough to seriously affect cellular processes like proliferation or differentiation.

PromoKine’s plant-derived cytokines and growth factors are free of animal components, serum traces, and antibiotics. They are also free of human, animal or bacterial infectious agents and have an endotoxin content typically 20-times lower than proteins produced in E. coli. Thus, they avoid problems caused by too high endotoxin levels and improve critical applications, e.g. in stem cell research.

The Optilab UT-rEX (UHPLC refractometer with EXtended range) is the first RI detector specifically designed for use with UHPLC systems using columns packed with small beads.


Using a combination of miniaturized components and cutting-edge semiconductor photodiode technology as well as proprietary computer algorithms, the UT-rEX presents a host of instrument firsts:

Besides UV, mass spectrometry, and evaporative light scattering, there has been no RI detector available for UHPLC applications until now. The linearity of the UT-rEX over a wide concentration range coupled with its sensitivity to samples that are not UV active, make it an exciting addition to UHPLC.

Considering the extremely small peak volumes of UHPLC, band broadening in the UT-rEX is kept to the absolute minimum, at less than 4 µL, as compared to 20-40 µL or more from other RI detectors. As a result, the superior resolution from UHPLC columns and instruments will not be compromised with the UT-rEX RI detector. 

In addition, the instrument has no range or gain settings. The full range of instrument detection is always present, and the full sensitivity exists over the entire range. The small flow cell and proprietary temperature regulation enable stable RI baselines and signals which further enhance the detector’s sensitivity.

The new Optilab UT-rEX can be operated below ambient temperatures as easily as above ambient. No hassle temperature control can be programmed down to 4°C or as high as 50°C. The Optilab UT-rEX is compatible with all UHPLC systems.
