Isolation and Characterization of CD34+ Cells from Cord Blood and CML Patients

Check if the same lab product or an alternative is used in the 5 most similar protocols
Details on the cell lines used in this study are available in Supplementary Methods. Primary mononuclear cells (MNCs) from discarded cord blood from the University Medical Center of El Paso (El Paso, TX, USA) were Ficoll-separated (Life Technologies, Carlsbad, CA, USA) and used for selection of the CD34+ population (StemCell Technologies Inc., Vancouver, Canada). CD34+ cells represent the disease-causing stem and progenitor population in CML. A purity of >90% was confirmed by flow cytometry using FITC anti-human CD34 (BioLegend Inc., San Diego, CA, USA). CD34+ cells from peripheral blood of CML patients or normal donors that were used for nucleocytoplasmic fractionation (see below) were obtained from the Centre for Haematology at Imperial College London (London, UK). Cells (2 × 106) were lysed directly for use in molecular biology assays. This study was approved by the Texas Tech University Health Sciences Center El Paso Institutional Review Board (IRB) and by the Imperial College Research Ethics Committee. All patients gave informed consent and all experiments were performed in accordance with the Declaration of Helsinki.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
