Pre-transfected MDA231-BrM2 cells were co-cultured for 24 hours with hCMEC/D3 monolayers, which were stably transduced with a lentivirus expressing a triple-fusion reporter (TGL) encoding firefly luciferase and green fluorescence protein (GFP).29 (link) GFP-expressing cancer cells were separated from unlabeled hCMEC/D3 by fluorescence-activated cell sorting (FACS) using the BD FACSAria™ III cell sorter (BD Biosciences, USA). The collected hCMEC/D3 cells were then lysed for western blot analysis according to standard procedures and as previously described.13 (link),15 (link) The following primary antibodies were used: Anti-Claudin 5 (4C3C2) (35–2500) 1/500 (Thermo Fisher Scientific), Anti-VE-cadherin (ab33168) 1/1000, Anti-MMP-1 (ab38929) 1/5000 (Abcam), and Anti-GAPDH (ab9485) 1/7500 (Abcam) (as loading control).

After particle flow (see above), cells were fixed with 4% PFA, washed twice with PBS 1%-BSA 0.2%-Triton for 5 min. Before and after hybridization with the primary antibody (anti-VE-cadherin Ab-33168 “Abcam” - Cambridge, UK) cells were washed with PBS 1%-BSA. Secondary antibody hybridization was performed using Alexa Fluor® 488 labeled anti-rabbit (Thermo Scientific, Waltham, MA, USA). Nuclei were stained using DAPI (Figs 3A and 4C). Images were taken using an Inverted Nikon FLUO-Scope (Nikon, Tokyo, Japan). Data were analyzed with Nikon software ND2. For particle immunofluorescence, samples were prepared as described above for flow cytometry. After particle conjugation with antibody, 105 particles were seeded on an 8-well Nunc® Lab-Tek® Chamber Slide™ (Thermo Scientific). Images were acquired with a Nikon A1 confocal imaging system and analyzed with Nikon NIS Elements software (Nikon).

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.
