Multicolor flow cytometry analysis of BM was performed at the day of diagnosis to assess leukemic-associated immunophenotype (LAIP) of blasts cells. A following antibodies were used for cell immunophenotyping: CD34-PE, CD45-PerCP, CD10-PE-Cy7, CD19-APC, CD38-AlexaFluor-700, CD20-APC H7, CD11a-BV510 (BD Biosciences, Waltham, MA, USA), CD58 (Beckman Coulter, Brea, CA, USA). On the day 15th and 33rd BM was analyzed using the same panel of antibodies to determine MRD. To the appropriate amount of BM (106 cells) antibodies listed above were added, samples were incubated for 20 min at room temperature in darkness. Erythrocytes were lysed for 10 min at room temperature in darkness with lysing solution (BD FACS Lysing Solution, Becton Dickinson Biosciences, San Jose, CA, USA), washed twice in PBS, and finally resuspended in 200 μL of PBS. For distinguishing nucleated cells, samples were stained with Syto®41 (Thermo Fisher Scientific, Waltham, MA, USA). FACS analysis was done using FACSCanto or FACSCanto10 with FACSDiva Sorfware v. 8.1 (Becton Dickinson Biosciences, San Jose, CA, USA).

HO-1 expression was assessed in BM of 11 patients upon diagnosis. Then in patients in whom, after routine MRD staining, there was a sufficient material for additional staining, an intracellular HO-1 staining was performed (6 children at day 15, 3 children at day 33). In this purpose 106 of bone marrow cells were stained with CD34-PE, CD45-PerCP, CD10-PE-Cy7, CD19-APC, CD38-AlexaFluor-700, CD20-APC H7, CD11a-BV510 (BD Biosciences, San Jose, CA, USA), lysed, fixed, and then permeabilized using a BD Intrasure Kit, according to the manufacturer’s instructions. After permeabilization step, cells were incubated with primary antibodies recognizing HO-1 (rabbit polyclonal, SPA 896, Enzo, Warszawa, Poland), washed twice, and stained with goat anti-rabbit secondary antibody conjugated with Alexa Fluor 488 (Life technologies, HITACHI, Tokyo, Japan). After two washing steps, samples were stained with Syto®41 (Thermo Fisher Scientific, Waltham, MA, USA) and analyzed using FACSCanto10 with FACSDiva Sorfware v 8.0.1 (Becton Dickinson Biosciences, San Jose, CA, USA).

Check if the same lab product or an alternative is used in the 5 most similar protocols
Flow MRD was performed according to the UK standardized method (13 (link)). Briefly, samples were collected into Acid Citrate Dextrose and with red cells lysed using a standard ammonium chloride procedure. Biomarker labeling was done using fluorescent-conjugated antibodies such as CD45-APCH7, CD10-PECy7, CD19-APC, CD34-PerCP (all from BD Biosciences, Plymouth, UK) and nuclear staining by Syto41 (Molecular probes, Loughborough, UK). Flow cytometric measurement was done on a BD FACs Canto II equipped with 488-nm (blue), 633-nm (red), and 405-nm (violet) lasers, with a target number of 50,000 cells for diagnostic samples and >300,000 for “on-treatment” samples. For analysis, an expert-guided sequential manual gating strategy was applied: Lymphoid cells were first gated on forward and side scatters, followed by CD19+, low side scatter cells, then refined inspection on CD19+CD34 and CD19+/CD34+ double positive cells. Finally, the expression of CD10 along with CD45 was assessed in the CD19+CD34+ and CD34CD19+ populations to discriminate ALL cells from normal B cells. Samples were considered positive if the number of leukemic cells identified was equal to or greater than 0.01% (i.e. the percentage of leukemic cells over the total number of nucleated cells), providing at least 50 clustered events were apparent.

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.
