Antibody against gapdh

Manufactured by Beyotime
Sourced in China

Antibody against GAPDH is a laboratory reagent used to detect the presence and quantify the levels of the GAPDH (Glyceraldehyde 3-phosphate dehydrogenase) protein in biological samples. GAPDH is a commonly used housekeeping gene and its expression is often used as a reference point in various experimental techniques.

Total cell lysates were prepared from either liver tissue or cultured cells by lysis using RIPA Lysis Buffer (Beyotime, China) containing 1% PMSF and homogenization using a vortex oscillator (Roche, USA). Protein concentrations were determined using an Enhanced BCA Protein Assay Kit (Beyotime, China). An equal volume of 5 X loading buffer was mixed with the samples, which were boiled for 10 minutes. After separation by 10% SDS-PAGE, the proteins were transferred to a 0.45 mm PVDF membrane and blocked for 2 hours with 5% non-fat dry milk at room temperature. Then, the membrane was incubated overnight at 4 °C with the appropriate primary antibody. After incubation with the secondary antibody for another hour, the membranes were developed with SuperSignal™ West Pico PLUS Chemiluminescent Substrate (Thermo, USA). The following primary antibodies were used. Antibodies against ACOX1 (A8091) and CPT1A (A5307) were purchased from ABclonal, and an antibody against AHR (#4685) was purchased from Cell Signaling Technology (Danvers, MA, USA). The antibody against GAPDH (AG019) was purchased from Beyotime Biotechnology.

A lysis buffer (Beyotime Institute of Biotechnology, Nantong, China) was used to prepare total protein extracts from cell lines as well as tumor tissues. Then, protein concentrations were evaluated by a BCA kit (Beyotime Institute of Biotechnology, Nantong, China). An equal protein amount (40 μg per lane) was separated by SDS-polyacrylamide gel electrophoresis (PAGE) in 12% acrylamide gels and transferred onto polyvinylidine difluoride (PVDF) membranes (Millipore Corporation, Billerica, USA) which were blocked in 5% fat-free milk followed by overnight incubation at 4°C with the rabbit anti-NUF2 primary antibody (1 : 5000 dilution; Sangon Biotech, Shanghai, China). The secondary antibody was horseradish peroxidase- (HRP-) conjugated goat anti-rabbit antibody (1 : 2000; Beyotime Institute of Biotechnology). After stripping, the membrane was reprobed overnight at 4°C with antibody against GAPDH (1 : 2000; Beyotime Institute of Biotechnology), followed by incubation with secondary antibodies as above at room temperature (RT) for 2 h. An enhanced chemiluminescence system (ECL; Beyotime Institute of Biotechnology) was used for band visualization. The band intensities were quantified by densitometry.

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.
