Check if the same lab product or an alternative is used in the 5 most similar protocols
A sandwich ELISA to detect the rGAPDH as a mid-term PMI marker in rat kidney was performed using different epitope polyclonal antibodies. Briefly, the ELISA plates were coated with 50 μL goat polyclonal GAPDH antibody (0.5 μg/mL, sc-20357, Santa Cruz Biotechnology) and incubated at 4°C overnight. Tris-base saline containing 1% (w/v) BSA was added to prevent non-specific binding for 2 h at room temperature. The plates were washed with TBST buffer. Serially diluted rGAPDH proteins are added to the plates at 0–100 ng/μL and incubated for 1 h 30 min at 37°C. After washing, rabbit polyclonal GAPDH antibody (1:1000, sc-25778, Santa Cruz Biotechnology) was added and incubated for 2 h at room temperature followed by washing. Bound antibodies were detected with HRP-conjugated goat anti-rabbit IgG antibody (1:1000, sc-2004, Santa Cruz Biotechnology) and revealed using 3,3’,5,5’-tetramethylbenzidine dye. Absorbance was measured at 450 nm using a microplate reader (SunriseTM, Tecan, Basel, Switzerland).

Cleaved caspase-3 immunohistochemistry and terminal deoxyribonucleotide transferase (TdT)-mediated nick-end labeling (TUNEL) staining was performed to detect apoptotic cells in SCC4 tumor tissues of 5 study groups using paraffin-embedded sections of SCC4 tumor tissues. After fixation with cold acetone for 20 min, samples were incubated with a 1:300 dilution of rabbit polyclonal cleaved caspase-3 (Asp175) antibody (#9661, Cell signaling, Danvers, MA, US) at 4 °C for 1 h followed by incubation with HRP conjugated goat anti-rabbit IgG antibody (1:200, Santa Cruz Biotechnology, Santa Cruz, CA) for 30 min. Visualization of cleaved caspase-3 was achieved with a DAB detection kit (Pierce, Rockland, IL). TUNEL assay was performed in 5 study groups using an in situ cell death detection kit, POD, TUNEL System (Roche, Basel, Switzerland). This detection kit is based on the detection of single-and double-stranded DNA breaks that occur at the early stages of apoptosis. Cell nuclei with DAB substrate staining were defined as TUNEL-positive nuclei. TUNEL-positive nuclei were monitored. All specimens were examined with an Olympus BX53 light microscope (Olympus Corp., Tokyo, JP). Multiple (7 images) tumor images of cleaved caspase-3 and Tunel on high power (400×) of 5 groups were obtained using software image for analysis.

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.
