BMNCs in IR group and IR+SVP-B5 group were collected 2 h after injection of saline or SVP-B5, IR+ group and IR++SVP-B5 group were treated as described above and B MNCS were collected at 7d and 14d after TBI. The BMNCs were fixed with 100% ethanol for 5 min. The samples were centrifuged and the cells were incubated with 0.1% PBS-Tween for 20 min and centrifuged. After washing with 0.1% PBS-Tween, a mixture of 10% goat serum/PBS/0.3 M glycine was added and the sample was mixed well and placed at 22 °C for 30 min. The non-specific reaction between proteins was blocked. The sample was washed and a sample of 100 μl γH2AX antibody (Abcam, USA)diluted 1:500 was added, and incubated at 22 °C for 30 min. The sample was washed and centrifuged and the supernatant was discarded. The pellets were treated with 100 μl secondary antibody (DyLight® 488 goat anti-mouse IgG) (H+L) (Abcam, USA) diluted 1:500 and incubated at 22 °C for 30 min, washed and centrifuged. Subsequently, 0.5 ml 0.1% PBS-Tween was added, and the γH2AX level was detected by flow cytometry at the FITC wavelength.

PC12 cells were seeded at 4 × 104 cells /mL and incubated for 24, 48, 72 and 96 h. Following incubation, the cells were fixed with 80% ice-cold methanol (Thermo Fisher Scientific, Waltham, MA, USA) for 5 min and the methanol was removed. After permeabilisation with 0.1% PBS/Tween for 20 min, cells were incubated in a blocking solution consisting of 10% Bovine Serum Albumin (BSA) with 0.3 M glycine (Sigma-Aldrich, St. Louis, MO, USA) with primary monoclonal antibodies for HIF-1α (ab16066) (Abcam, Cambridge, UK) at a concentration of 2 µg/1 × 106 cells and incubated for 30 min at 22 °C. The primary antibody-blocking solution was then removed via centrifugation at 300× g for 3 min. The cells were washed with PBS, centrifuged for 3 min at 300× g and then incubated with 500 µL of secondary antibody DyLight 488 goat anti-mouse IgG (H + L) (Abcam, Cambridge, UK) (1/500 dilution) for 30 min at 22 °C. An FC500 flow cytometer (Beckman Coulter, Brea, CA, USA) was used to analyse the samples. At least 10,000 events were collected per sample. Data were analysed using Flowing Software (Turku Centre for Biotechnology, Turku, Finland).

Mitochondrial Changes in Human Cardiac Cells

Morphological changes and mitochondrial activity of human cardiac cells were studied through a Confocal Laser Scanning Microscope (EZ-C1-Nikon). Briefly, human cardiac cells were untreated (control) or treated with DOXO alone or combined with DAPA for 24 h. After incubation, cardiomyocytes were fixed in 4% formaldehyde (10 min) and then incubated in 1% BSA/10% normal goat serum/0.3 M glycine in 0.1% PBS-Tween20 for 1 h to permeabilize the cells and block non-specific protein–protein interactions. The cardiomyocytes were then incubated with an anti-Mitochondria antibody (113-1)—BSA and Azide free (Abcam ab92824, Milan, Italy) 5 µg/ml overnight at ±4°C. As a secondary antibody (green), a DyLight® 488 goat anti-mouse IgG (H ± L) (ab96879, Abcam, Milan, Italy) was used at a dilution of 1/250 for 1 h. Membrane staining was obtained using Concanavalin A Tetramethylrhodamine Conjugate (Invitrogen, Life Technology, Milan, Italy) at a final concentration of 100 µg/ml. Through a confocal microscope (C1-Nikon) equipped with EZ-C1 software for data acquisition and 60× oil immersion objective, intracellular mitochondria were imaged through excitation/emission at 488/518 nm and cell membrane through excitation/emission at 555/580 nm (31 (link)).

Quantifying Neurogenic Markers in ADMSCs

Check if the same lab product or an alternative is used in the 5 most similar protocols
On day 1 after the second step of induction, the ADMSCs were subjected to flow cytometry to quantify the proportion of cells with positive neurogenic markers. The cells were fixed using 4% paraformaldehyde at room temperature for 30 min and permeabilized using 0.1% TritonX-100+2% BSA in PBS at 37°C for another 30 min. Then the cells were incubated with primary anti-NSE antibody (1:100, ab53025, Abcam) for one hour, anti-GFAP (1:100, ab10062, Abcam) for 30 min or anti-Tuj-1 (1:100, ab18207, Abcam) for 30 min. For anti NSE and anti-Tuj-1, the secondary antibody used was Alexa Fluor® 488 goat anti-rabbit IgG (H&L) (1:4000, ab150077, Abcam) for 30 min at 22°C. For anti-GFAP, the secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (1:500, ab96879, Abcam) for 30 min at 22°C. The proportion of cells with active neuronal markers were then analyzed using a FACSCaliber (BD Biosciences, Franklin Lakes, NJ, USA). Data acquisition was done using CellQuest 3.2 software (BD Biosciences). Each test was performed with at least three repeats.

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.
