Fluorescent Microspheres and Nup153 in HeLa Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
In this work, three samples were prepared, including two kinds of fluorescent microspheres (40 nm and 100 nm in diameter) and human Nup153 (a protein as an essential component of the basket of nuclear pore complexes in vertebrates is encoded by the Nup153 gene) in fixed HeLa cells. The preparation of 40 nm fluorescent microspheres (FluoSpheres carboxylate-modified, 0.04 μm, dark red [660/680]; Invitrogen) was as follows: (a) a microsphere solution (4 μL) was diluted at a ratio of 1:500 in 2 mL distilled water, (b) the diluted solution (5 μL) was attached to a cover slip and then mounted on a glass slide in 97% 2,20-thiodiethanol until the solvent completely evaporated and (c) the sample was sealed with nail polish. The preparation of 100 nm fluorescent microspheres (TetraSpeck microspheres, 0.1 μm, blue/green/orange/dark red; Invitrogen) used similar steps except the dilution ratio. To prepare the HeLa cell sample, the detection of Anti-Nup153 (Abcam, Cambridge, UK) was performed using secondary antibodies labeled with Star 635P (Abberior, Göttingen, Germany). A detailed description of the steps can be found in [18 (link)].

The cell lysates were separated by 10% SDS-PAGE and then transferred to PVDF membranes (Millipore) using standard electroblotting procedures. The blots were then blocked and incubated overnight at 4 °C with anti-NUP153 (Abcam, Cambridge, MA, USA), anti-VEGF (Abcam), anti-basic fibroblast growth factor (Abcam), anti-hepatocyte growth factor (Abcam), and anti-tubulin (Millipore) primary antibodies. Immunolabeling was detected using an enhanced chemiluminescence kit (GE Healthcare, Pittsburgh, PA, USA) according to the manufacturer's instructions.

The following primary antibodies were used: mouse monoclonal antibodies against LB1 (Zymed, San Francisco, CA, USA); LB2 (Abcam, Cambridge, MA, USA); LA/C (Millipore, Billerica, MA, USA); rabbit polyclonal antiserum against LB1 (Abcam); LA/C (Santa Cruz Biotechnology, Santa Cruz, CA, USA), trimethyl histone H3 (Lys27) (Millipore); γ-tubulin, β-tubulin and β-actin (Sigma, St. Louis, MO, USA); and BU1/75 (ICR1) rat monoclonal anti-BrdU antibody (Abcam). To analyze the localization of nuclear components, the following primary antibodies were used: anti-Nup153 (Abcam), anti-nuclear pore complex (mab 414; Covance, Princeton, NJ, USA), anti-sc-35 (Sigma), anti-LAP2β (BD Biosciences, San Diego, CA, USA), and anti-fibrillarin (Cytoskeleton Denver, CO, USA) mouse monoclonal antibodies, as well as antiactivated RNA Polymerase II monoclonal IgM (Covance).

Cell culture FAK-deficient Squamous Cell Carcinoma (SCC) cell lines were generated as described previously (18) . SCCs were maintained in Glasgow MEM containing 10% FCS, 2 mM L-glutamine, nonessential amino acids, sodium pyruvate and MEM vitamins at 37°C, 5% CO 2 . SCC FAK-WT cells were maintained in 1 mg/ml hygromycin B. siRNA FAK-WT or FAK -/-SCC cells were transiently transfected using HiPerFect (Qiagen, Manchester, UK), according to manufacturer's protocol with a final concentration of 80 or 100 nM siRNA respectively (Supplementary Material and Methods, Table 1). Cells were analyzed at 48 h post transfection.

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.
