  • Easy to Use Anti-Human HLA-E Antibody for Flow Cytometry

    Tuesday, December 19, 2023
    HLA proteins are key membrane proteins to understand the interaction between target cells and the immune system. HLA-E is one of these proteins. It does not interact a lot with T cells but it does interact a lot with NK cells by providing inhibitory signals preventing the NK degranulation. I use ... read more
  • Decent Antibody to Measure HLA-C Expression by Flow Cytometry

    Tuesday, December 19, 2023
    HLA-C membrane protein is part of the Class I HLA proteins that play a huge role in the mechanism of rejection. HLA-C is recognized by CD8 T cells that are triggered in case of HLA mismatches between donor and recipient. In general, I use Class I HLA antibody to determine the level of expression of... read more
  • Not Reliable Multichannel 200 µL Pipette

    Tuesday, February 07, 2023
    I work a lot in cell culture so it is very important for me to have reliable equipment for routine tasks in cell culture. I do not recommend this product because one channel does not suck up the same volume as the others. And furthermore, this channel is in the middle of the pipette which is not ... read more
  • Efficient Molecule to Improve HDR Efficiency of CRISPR-Cas9

    Monday, February 06, 2023
    I perform a lot of CRISPR-Cas9 genome editing experiments and I started recently to insert point mutations instead of simply doing a knock-out. This product does increase the rate of HDR events which is quite low in general. I recommend using this product but be careful with the incubation time as ... read more
  • Easy to Use Reagent to Perform CRISPR-Cas9

    Thursday, February 02, 2023
    I perform a lot of CRISPR-Cas9 experiments on cells such as B cells, T cells and HEK293T. My protocol to modify genes uses electroporation of Cas9 RNP complex because it leads to less "off-target" events. This product (tracrRNA) is part of the RNP complex. It is very easy to use and I recommend ... read more
  • Efficient Molecule to Increase Knock-out Efficiency

    Monday, January 30, 2023
    I perform CRISPR-Cas9 genome editing on different type of cells such as HEK293T, T cells and B cells. One very important result of those experiments is the knock-out efficiency. Through my experiments, I noticed a much higher efficiency using this product during electroporations of Cas9 RNP. Thus, I... read more
  • Efficient Cas9 Protein for Genome Editing

    Thursday, January 26, 2023
    I use this product to perform CRISPR-Cas9 genome editing on cells such as HEK293T, B cells and T cells. Using protein instead of DNA plasmid decreases the risk of off-target events, which can be very important in some cases. I recommend this product because it is reliable, and very easy to use. ... read more
  • 96-well Plate to Quantify Immune Response

    Wednesday, January 25, 2023
    I used this product to quantify supernatant fluorescence after co-culturing NK cells with fluorescent target cells such as HEK293T and B-EBV cells to highlight a difference in immune response. I recommend this product as it is very easy to use, even if it is disposable. read more
  • Efficient Way to Measure Cell Proliferation

    Tuesday, December 20, 2022
    I used this product to quantify the immune response of CD8+ cells co-cultured with different types of cells. Cells that do not proliferate are CTV positive whereas cells proliferating become less and less CTV positive. I recommend this product because it is easy to use even if my very first results ... read more
