摘要： In order to produce a more well defined interface between adjacent cell layers in a centrifuged sample of anticoagulated whole blood, a material which will bond one group of cells together is added to the blood sample prior to centrifugation. The bonding material must produce a high strength bond between one group of cells, but not effect the other cell types. The material is added prior to centrifugation of the blood sample.

摘要： A method for calibrating an instrument for using that instrument to obtain at least one light-related signal from particles under analysis comprises directing an incident beam of light at calibration particles having one or more known characteristics related to the particles expected to be analyzed. Both a light signal and a noise signal from the calibration particles are detected. A measurement is made of the ratio of the detected light signal to the detected noise signal, and that measurement is reported. The measured ratio is then compared to a predetermined ratio which represents a threshold for minimum instrument performance. This method further includes adjusting, if the predetermined ratio has not been attained, the operation of the instrument, while the calibration particles are within the incident beam of light, until the measured ratio reaches the predetermined ratio whereby the instrument is calibrated for subsequently obtaining the light signal from particles to be analyzed. A kit of reagents for use in calibrating an instrument for performing two-color analysis of particles and particle standards for calibrating fluorescence analysis instruments are also part of the instant invention.

摘要： One or more population of cells enriched for human hematopoietic stem cells is disclosed. HSC in this population of cells are capable of limited self-renewal and are capable of differentiating into all elements of the hematopoietic system. This population of cells has the phenotype of CD34.sup.+ /CD38.sup.- and more preferably CD34.sup.+ /CD38.sup.- /HLA-DR.sup.+. Cells within this population have been found to express CD13, CD33 and CD71. Hematopoietic stem cells can be used in a number of therapies, including autologous transplantation and in gene therapy.
