How to Perform an Absorbance-Based Readout (for HemoLIGHT™ PMT "Global")

Complete, "global" absorbance assay to monitor hematopoietic and immune reconstitution after stem cell transplantation.

Determine "global" hematopoietic stem and progenitor cell reconstitution.

  • An alternative to, or replacement for the classic colony-forming unit (CFU) assay for hematopoietic lineage engraftment and reconstitution.
  • Measurement of progenitor cell proliferation, rather than differentiation, provides faster results.
  • Measures individual hematopoietic lineages, providing a faster prediction of possible reconstitution than the “classic” CFU assay.
  • No colony counting required.
  • Results in 7 days.
  • Transforms the subjective CFU assay into an instrument-based, quantitative assay.
  • Simple and faster to use than any traditional CFU assay, even using automated colony counting.
  • Complete assay kit; includes everything needed to culture and measure hematopoietic cell growth.
  • Incorporates proven Suspension Expansion Culture™ (SEC™) Technology.

Principle of Using HemoLIGHT PMT Assays to Monitor Patient Reconstitution After Stem Cell Transplantation Using an Absorbance / Colorimetric Readout
 
  • Incorporates a terazolium WST-1 reagent that is reduced to a soluble yellow formazan, which can be measured at an maximum absorbance of 440nm (420nm to 480nm) in an absorbance plate reader.
  • After culture, add 10μl of the WST-1 reagent, mix and read absorbance at 440nm after 1-4 hours in a 96-well plate reader. Plates can be returned to incubator and re-read at a later time for increased sensitivity.
  • No solubilization step as in a MTT reaction. Replaces MTT assays.
HemoLIGHT™ PMT "Global" Assay Kits are available as:
  • 4-Population "Global" Assay consists of: SC-GEMM 1, P-BFU 1, P-GM 1, P-Mk 1 and Background
  • 5-Population "Global" Assay consists of: SC-HPP 2, SC-GEMM 1, P-BFU 1, P-GM 1, P-Mk 1 and Background
  • 7-Population "Global" Assay consists of: SC-HPP 2, SC-GEMM 1, P-BFU 1, P-GM 1, P-Mk 1, P-Tcell 3, P-Bcell 2 and Background
Each HemoLIGHT™ PMT "Global" Assay Kit contains 5, 6 or 8 x 96-well plates, one for each lineage and background. Each sample is meant to be assessed in 8 replicates, but can be reduced to 4 replicates. Therefore, if using 8 replicates/sample, 12 samples can be assessed using a single assay kit.
  • Peripheral blood
  • Bone marrow (biopsy)

For Research Use Only. Not for clinical diagnostic use.

An absorbance or multimode plate reader to measure absorbance at 490nm.

  • HemoLIGHT™ PMT "Global" Master Mixes for each cell population to be determined
  • WST-1 reagent
  • Sterile, clear, 96-well plate(s)
  • Sterile adhesive cover foils for maintaining unused well sterile
