IMMUNO-TROL Low Cells provide the same quality and reproducibility as IMMUNO-TROL Cells in a quality control product for low-level CD4 counts. IMMUNO-TROL Low Cells also provide open vial stability of 90 days for decreased waste.

IMMUNO-TROL Cells are a positive process control for flow cytometry. They are assayed for lymphocyte, granulocyte and monocyte specific antigens and single platform absolute counts.

The LeukoSure Enumeration Kit is comprised of a set of reagents used to prepare and enumerate white blood cells in leukoreduced red blood cell and platelet products by flow cytometry. The enumeration method depends upon mixing a known volume (100 μL) of LeukoSure Fluorospheres with an identical volume of sample to be tested. After analysis the absolute count for the specimen is calculated. This represents the absolute number of leukocytes in the specimen. The specimen is lysed and permeabilized using the LeukoSure Lyse Reagent to eliminate RBCs and prepare the cells for subsequent addition of the LeukoSure Stain Reagent which contains propidium iodide and RNAse (enzyme used to remove ribonucleic acid, or RNA). In the absence of RNA, propidium iodide binds only to double stranded deoxyribonucleic acid (DNA) so that nucleated cells in the sample emit fluorescence in proportion to their DNA content. The flow cytometer measures the fluorescence from each stained cell as it passes through the laser beam. Since mature platelets and red blood cells do not contain DNA, the stained cells represent the leukocyte component of the blood.

Echo® Qualified 384-Well Polypropylene (PP) Source Microplates ensure accurate and precise transfer with the Echo® Liquid Handler. This microplate is highly resistant to solvents including DMSO and buffers making it ideal for compound and sample storage.

394263. The (formerly AP384) P30 tips with filter are designed exclusively for the Biomek 384-multichannel head Laboratory Automation Workstation. Filtered tips reduce the chance of sample cross-contamination from aerosols. Like all our pipette tips, the P30 tips are made of 100% premium grade polypropylene and are guaranteed to be free of DNA, DNase/RNase, PCR inhibition, pyrogen/endotoxin and trace metals. Capacity for each tip (including air gaps) is 15 μL. Case of 10 racks.
