    Alomone Labs trpv1 epitope specific peptide
    Expression and functional analysis of <t>TRPV1</t> in BMMs and Osteoclasts. (a) BMMs stained for the macrophage marker CD11b (red) and TRPV1 (green) depict the latter’s expression in these cells, both in the absence (upper panel) and presence (lower panel) of RANKL. (b) Expression of TRPV1 (red) in phalloidin-stained osteoclasts (green, upper panel) is confirmed by a peptide segment against anti-TRPV1 antibody (lower panel) that reduces the specific fluorescence signal intensity of the TRPV1 channel.

    Functional analysis of TRPV1 in BMMs grown on the CMT:HEMA hydrogel. (a) BMMs grown on hydrogels to check for the endogenous levels of Ca 2+ using Fluo4-AM Ca 2+ -sensitive dye. TRPV1 activation elevates the intracellular Ca 2+ levels, as is quantified in (b); n = 100 cells; one-way ANOVA; ns: non-significant, **** p < 0.0001. (c) Correlation representation of the area of cells and per unit area intensity of Fluo4-AM depicts strong positive correlations under basal and TRPV1-activated conditions but not upon inhibition of the channel.
