Vibratome sections (100 μm thick) from virus-injected animals were immunolabeled with antibodies against mCherry, which was expressed from the virus, as well as antibodies against the mossy fiber marker, ZnT3. CellProfiler (Version 2.1.0) software was used to quantify the degree of overlap between mCherry and ZnT3. The average amount of overlap was 70%.
Primary antibodies: rat BrdU (AbD Serotec, MCA2060GA, 1:500), rabbit GFP (Invitrogen, A11122, 1:300), rabbit Complexin-1 (Proteintech, 10246–2–AP, 1:300), mouse GFAP (G6171, 1:500), mouse Nsf-1 (MA1–12435, 1:300) and rabbit Syn3 (OSS00018W, 1:300) from Thermo Scientific, guinea pig Iba1 (234 004, 1:500), mouse Syt1 (105 011, 1:300), guinea pig ZnT3 (197 004, 1:1000) from Synaptic Systems.
Secondary antibodies. Antibodies (all obtained from Jackson Laboratory, donkey anti-guinea pig IgG (H+L) ML, #706-225-148 and 706-175-148; donkey anti-mouse IgG (H+L) ML, #715-225-151, 715-165-151, and 715-175-151; donkey anti-rabbit IgG (H+L) ML, #711-225-152, 711-165-152, and 711-175-152 were diluted 1:400. Confocal scans were carried out using a LSM 510 Imager Z.1 microscope (Zeiss) using Plan-Apochromat 63X/1.4 and EC Plan-Neofluar 40X/1.30 oil immersion objective lenses and four excitation laser lines. Tile scans were performed using a LSM 710 confocal microscope (Zeiss) with a Plan-Apochromat 20X/0.8 objective.

The cells used for morphological analysis were imaged using an Achroplan 20x/0.45 objective or an EC Plan-NEOFLUAR 40x/1.3 oil objective on a Zeiss Axioskop 40 fluorescent microscope system with the Axiocam 506 mono high resolution camera and the ZEN 2 lite software from Zeiss.

Immunofluorescence was performed as previously described8 (link)40 (link). Briefly, cultured cells or tissue sections were fixed with MeOH at −20 °C for 2 min, blocked on ice using Blocking One (Nacalai Tesque), and then sequentially incubated with appropriate primary and secondary antibodies at room temperature. DNA was stained with 100 ng/mL 4′-6-diamidino-2-phenylindole (DAPI; Sigma-Aldrich), and stained samples were viewed under an IX83 fluorescence microscope with UPlan FL N 40x/0.75 and PlanApo N 60x/1.42 objective lenses (Olympus, Tokyo, Japan) or an LSM710 confocal microscope with EC Plan-NEO FLUAR 40x/1.3 and Plan APOCHROMAT 63x/1.4 objective lenses (Carl Zeiss, Jena, Germany). Composite figures were prepared using Photoshop CS5.

Cells were grown on glass-bottomed dishes (FluoroDish, World Precision Instruments Inc.) for 24 h before the addition of 5 ng/ml TGFβ1. AFM force curves were obtained using a Bruker Nanowizard 4A instrument coupled with a Zeiss Observer.Z1 Microscope with LSM5 Exciter laser scanning confocal module and ×40 oil immersion objective lens (Zeiss, EC Plan-NeoFluar 40X/1.3). A nitride tip (Bruker, SAA_SPH-5UM) with a nitride lever was used. All the force curves were analyzed using the JPKSPM Data Processing Software.

Breast Cancer Cell Antibody Staining

Check if the same lab product or an alternative is used in the 5 most similar protocols
Conventional antibody staining of cultured breast cancer cells was described in detail previously [29, 66] . The antibodies used for conventional antibody staining were identical to the antibodies used for the PLA and were used in the same concentration. Pictures were taken with a Zeiss LSM700 confocal laser scanning microscope, using a 40x oil immersion objective (EC Plan-Neofluar 40x/1.3; Carl Zeiss AG).

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.
