Anti β actin antibody

Manufactured by Affinity Biosciences
Sourced in United States, China

The Anti-β-actin antibody is a primary antibody that specifically binds to the β-actin protein. β-actin is a ubiquitously expressed cytoskeletal protein that plays a fundamental role in various cellular processes. This antibody can be used for the detection and quantification of β-actin in various experimental techniques, such as Western blotting, immunohistochemistry, and immunocytochemistry.

SW-60, Lovo, HCT-116, NCM460, and HEK293 cells were grown and routinely maintained in Dulbecco modified Eagle medium (DMEM) supplemented with 10% fetal bovine serum (FBS), 100 U/mL penicillin, and 100 mg/mL streptomycin. Cells were cultured at 37°Cin 5% CO2 and 95% humidified air. For establishment of stable MAGP2 overexpressing cells, overexpressing plasmid was constructed by Inovogen, China; then, the plasmid was packed by a lentivirus system (Inovogen, China). After removing the medium of the cells, the lentiviral supernatant was added (with 6 μg/mL polybrene). After 1 day, the supernatant was removed, and the cells were screened for 2 weeks using 10 μg/mL puromycin (Sigma-Aldrich, Shanghai, China). Anti-MAGP2 antibodies were purchased from Abcam (ab171737; Shanghai, China); anti-β-actin antibodies were purchased from Affinity Biosciences (AF7018; Guangzhou, China).

Total protein was extracted from RCSECs and rat choroid tissues. The samples were gently washed with PBS three times and then incubated for 15 min in lysis buffer. Total proteins were collected by centrifugation at 12,000×g for 10 min, and the precipitates were discarded. The proteins (20 µg) were separated by SDS-polyacrylamide gel electrophoresis and transferred to PVDF membranes. The nonspecific binding sites were blocked with TBST supplemented with 10% skim milk powder at 37 °C for 1 h, and then the membranes were incubated with specific antibodies at 4 °C overnight. Anti-β-actin antibodies (1:10,000, Affinity, China) were used as the internal control. After incubation with a secondary antibody, an enhanced chemiluminescent reagent (BioTech, Beijing, China) was used to detect the antibodies.

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.
