Western Blot Analysis of Staphylococcus aureus Hla

Check if the same lab product or an alternative is used in the 5 most similar protocols
Western blots were performed as previously described [37 (link)]. Briefly, ST764 isolates (six randomly selected isolates each in t002 isolates and t1084 isolates, and these isolates same apply to the experiment that follows) were grown in TSB with shaking for 24 h and bacterial culture supernatants were collected. The protein concentration of each sample was determined by Bradford assays to keep the total amount of protein loaded for SDS-PAGE consistent in the twelve isolates. Proteins were mixed with Omni-EasyTM Protein Sample Loading Buffer (EpiZyme Biotechnology Co., Ltd., Shanghai, China) and heated for 10 min at 95°C. Samples were separated by 12.5% SDS-PAGE and were transferred to the PVDF membrane. After blocking with 5% bovine serum albumin (BSA) at 4°C for overnight, the membrane was incubated with a rabbit anti-Hla IgG antibody (Sigma) at a 1/2500 dilution. The membrane was then incubated with Goat Anti-Rabbit IgG HRP (Biosharp) at a 1/5000 dilution. Omni-ECLTM Pico Light Chemiluminescence Kit (EpiZyme Biotechnology Co., Ltd., Shanghai, China) was used to develop image.

After 24 h of aloin, chloroquine, rapamycin and starvation administration, HOS and MG-63 cell lines were lysed in RIPA buffer with protease and phosphatase inhibitor cocktail. Protein samples of same amount were separated by western blot. Blot intensity was analyzed by Image J (v1.51). The primary antibodies applied in this research were as follows: AKT, ATG5, Beclin1, Bcl-2, bcl-xl, cleaved caspase 3, cleaved caspase 7, cleaved caspase 9, cleaved PARP, mTOR, pho-mTOR (SER2448), pho-AKT (SER473), PI3Kα (p110), SQSTM1 (P62), LC3B. Beta-actin was used as internal reference. The secondary antibodies were as follows: goat anti-rabbit IgG–HRP (1:2000, Biosharp) and goat anti-mouse IgG–HRP (1:2000, Biosharp).

Total protein was extracted from cells and tissues using RIPA lysis buffer (#P0013B, Beyotime, Beijing, China). Protein concentrations were quantified using the BCA protein assay kit (#BL521A, Biosharp, Beijing, China). Protein samples were mixed with SDS–PAGE loading buffer (#MB2479, Meilunbio, Dalian, China), separated on a SDS-PAGE gel, and transferred to PVDF membranes. The membranes were incubated overnight at 4°C with primary antibodies against TNFα (26405-1-AP, 1:2000, Proteintech), phosphorylated P65 (p-P65) (AP0475, 1:2000, ABCLONAL, Woburn, MA, USA), total P65 (66535-1-Ig, 1:2000, Proteintech), and GAPDH (10494-1-AP, 1:5000, Proteintech). Next, the membranes were incubated with goat anti-rabbit IgG-HRP (BL003A, 1:5000, Biosharp) or goat anti-mouse IgG-HRP (BL001A, 1:5000, Biosharp) secondary antibodies. ECL color exposure was used to detect immunoreactive bands. An Odyssey Infrared Imaging System (Li-COR Biosciences, Lincoln, NE, USA) was used to quantify protein bands, using GAPDH as the internal reference.

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.
