doi: 10.1371/journal.pone.0316854
Figure Lengend Snippet: HUVEC transfected with either mRFP-Halo ( A ) or mRFP-Halo-LAMP1 ( B ) were incubated with 1 µM MaPCa-656 low for 2 h at 37 °C and subjected to live cell microscopy. Note that not all mRFP-Halo-LAMP1 positive lysosomes show enhanced MaPCa-656 low fluorescence. Shown are confocal microscopy images displaying maximum intensity projections of z-stacks. Note the cytosolic (A) or lysosomal recruitment (B) of the Ca 2+ indicator MaPCa-656 low . Scale bars: 10 μm.
Article Snippet: Rev VWF-mRFP backbone 5´-TTGTACAGGGCGCCGGTG . mRFP-Halo-LAMP1 was obtained by exchanging RpHLuorin2 in LAMP1-RpHLuorin2 (Addgene #171720) with mRFP-Halo amplified from VWF-mRFP-Halo using NEBuilder Hifi DNA Assembly.
