  • Detection of LPA Receptor 6 In Microglia Cells

    Tuesday, November 28, 2023
    The Ab was used to detect changes in LPAR6 expression in untreated or LPS-treated (20 ng/mL for 24 h) BV-2 cells. It did work as expected, observing a band at the correct MW. However, in our case we also had some unspecific bindings at higher molecular weights. Apart from that, the antibody is quite... read more
  • Best Antibody for LPAR5 Detection Via WB

    Tuesday, November 28, 2023
    When I started using this antibody, not many were available in the market. I still believe it is the best for detection of LPAR5 expression by immunoblotting. In the current study, we used it to investigate changes in LPAR5 expression under inflammatory conditions (LPS treatments in BV-2 microglial ... read more
  • A Good Antibody for LPA2 Studies

    Tuesday, November 28, 2023
    As part of our study, we sought to investigate changes in LPAR2 expression after treatment with LPS. Even though the Ab reactivity is against human, we successfully used it to detect LPAR2 in a murine microglial cell line. Even though it has to be used at a 1:250 dilution, the Ab gives only one ... read more
  • Detection of LPAR3 Expression Using Immunoblotting

    Tuesday, November 28, 2023
    The antibody was used to study the impact of LPS treatment on LPAR3 expression in BV-2 cells by Western blotting. The product has been often used by our lab during previous experiments providing us with clear, reproducible results. A band at the expected MW was detected using the Ab at 1:400 ... read more
  • Assessment of Synaptophysin Expression in Murine Brain Tissue

    Tuesday, November 07, 2023
    The antibody was used to detect changes in the expression of synaptophysin in a mouse model of neuroinflammation using immunoblotting. The antibody was used previously for IHC experiments, providing really clear staining with minimal background. For the western blot experiments, we observed only one... read more
  • An Unexpectedly Good Ab for TLR4 Detection

    Tuesday, November 07, 2023
    The antibody was used to detect changes in TLR4 expression using immunoblotting. The aim was to assess whether inhibition of ATX (PF-8380) would impact the LPS induced increased expression in mouse brain tissue. Despite our concerns for unspecific binding, we observed only one band at the expected ... read more
  • Evaluation of Microgliosis in Mouse Brain

    Tuesday, November 07, 2023
    The specific antibody is very popular, being extensively used in immunofluorescence experiments as a marker of microglia activation. For the current experiments, we wanted to assess changes in Iba1 expression in mouse brain tissue using immunoblotting. Having worked flawlessly in IF experiments, the... read more
  • Detection of GFAP in A Mouse Model of Neuroinflammation

    Tuesday, November 07, 2023
    The goal of our experiment was to detect changes in GFAP expression after blocking the ATX-LPARs pathway in a mouse model of neuroinflammation. The antibody was used at the recommended dilution 1:1000, giving good and reproducible results. In some cases, a fade unspecific band was observed but at ... read more
  • Detection of COX2 in Brain Samples

    Tuesday, November 07, 2023
    The antibody was used to detect changes in COX2 expression in mouse brain tissue using immunoblotting. Our aim was to study the effect of ATX inhibition (PF-8380) in different inflammatory markers. The antibody has been used numerous times in our lab, for assessing the expression of COX2 in samples ... read more
  • Quick Spin of Samples

    Monday, April 24, 2023
    This mini centrifuge offers quick spin of samples, reaching relatively high speeds. It has a braking function which stops the unit instantly when it is powered off or when you open the lid. We extensively use it to spin down samples after vortexing or thawing. It is very compact, small, and rather ... read more
