Phospho ros1

Manufactured by Cell Signaling Technology
Sourced in United States

Phospho-ROS1 is a primary antibody that recognizes the phosphorylated form of the ROS1 protein. ROS1 is a receptor tyrosine kinase that is involved in various cellular processes. The Phospho-ROS1 antibody can be used to detect and quantify the phosphorylated state of the ROS1 protein using techniques such as Western blotting or immunohistochemistry.

Where indicated, cells were treated with tyrosine kinase inhibitor for 2 to 4 hours. Lysates were prepared from cells using a standard cell lysis buffer as described before (21 (link)). Protein quantitation of cleared cell lysates was performed using Pierce™ BCA Protein Assay Kit (ThermoFisher Scientific), and 25 μg of total protein was loaded on pre-cast 4–12% Criterion™ XT Bis-Tris Protein Gels (Bio-Rad, # 3450125). Proteins were transferred to nitrocellulose membranes, and probed with phospho-ROS1 [#3078, 1:1,000; Cell Signaling Technology (CST)], total ROS1 (#3266, 1:1,000; CST), phospho-SHP2 (#3751, 1:1000, CST), total SHP2 (#3397, 1:1000; CST), phospho-ERK1/2 (#9101, 1:1,000; CST), total ERK2 (sc-1647, 1:2,000; Santa Cruz, phospho-Akt (#4060, 1:1,000; CST), AKT (#610860, 1:1,000; BD Transduction Laboratories). Blots were imaged using either a LI-COR Odyssey imaging system or the Bio-Rad ChemiDoc imaging station according to the manufacturer’s protocol for immunoblot detection with use of infrared dye or horseradish peroxidase-conjugated secondary antibodies, respectively. phospho-ROS1 detection required the SuperSignal™ West Femto Maximum Sensitivity Substrate (ThermoFisher Scientific).

Western blotting was performed as described previously.24 (link)–26 (link) Monoclonal antibody (mAb) against glyceraldehyde-3-phosphate dehydrogenase (GAPDH) antibody (G-9) (sc-365062) was used to standardize cytosolic protein loading on the sodium dodecyl sulfate-polyacrylamide gel electrophoresis. ROS1 (D4D6) rabbit mAbs from Cell Signaling Technology (catalog no: 3287) were used to recog-nize FIG-ROS1 and Phospho-ROS1 activity (Tyr2274) (catalog no: 3078). Anti-GOPC/FIG antibody (MyBioSource: MBS421395) was used to detect FIG expression. p-Met antibody (Tyr 1365) (sc-3408), p-Met (F-5) (sc-377548), p-ALK antibody (Tyr 1586) (sc-109905), Bim (H-191) (sc-11425), survivin (D-8) (sc-17779), Mcl-1 antibody (S-19) (sc-819), and p-Akt1/2/3 antibody (Ser 473)-R (sc-7985-R) were purchased from Santa Cruz Biotechnology, Inc. The secondary antibodies were horseradish peroxidase-conjugated goat anti-mouse immunoglobulin (Ig) G (ICN Biomedicals) and horseradish peroxidase-conjugated goat anti-rabbit IgG (ICN Biomedicals).

Ba/F3 CD74-ROS1 and CD74-ROS1D2033N cells were treated with the indicated concentrations of inhibitors for 2 h, pelleted, washed once in ice-cold PBS, and lysed in 200 µL of cell lysis buffer (Cell Signaling Technology) that was supplemented with 0.25% deoxycholate, 0.05% SDS, and protease and phosphatase inhibitors. Equal amounts of protein were extracted with SDS sample buffer for 15 min at 80°C and resolved on 4–15% Tris-glycine or 4–12% Bis-Tris precast gels (Criterion; Bio-Rad). Proteins transferred to Immobilon-FL membranes (Millipore) were probed with: phospho-ROS1 [Cell Signaling Technology (CST); 3078, 1:1000], total ROS1 (CST; 3266, 1:1000), phospho-ERK1/2 (CST; 9101, 1:1000), total ERK2 (Santa Cruz; sc-1647, 1:2000), phospho-AKT (CST; 4060, 1:1000), AKT (BD Transduction Laboratories; 610860, 1:1000), pSHP2 (CST; 3703), pSTAT3 (CST, 9131), and GAPDH (Ambion; AM4300, 1:5000). Blots were imaged using either a LI-COR Odyssey imaging system or the Bio-Rad ChemiDoc imaging station according to the manufacturer’s protocol for immunoblot detection with use of Infrared dye or horseradish peroxidase-conjugated secondary antibodies, respectively.

Immunoblotting and Phospho-Receptor Tyrosine Kinase Profiling

Check if the same lab product or an alternative is used in the 5 most similar protocols
The following antibodies were obtained from Cell Signaling Technology: phospho‐EGFR (Tyr1068), EGFR, phospho‐ALK (Tyr1282/1283), ALK, phospho‐ROS1 (Tyr2274), ROS1, phospho‐ERK1/2 (Thr202/Tyr204), ERK1/2, phospho‐AKT (Ser473), AKT, GAPDH, and horseradish peroxidase‐conjugated anti‐rabbit IgG antibody.
For immunoblotting, cells were harvested, washed in phosphate‐buffered saline, and lysed in radioimmunoprecipitation assay buffer (1% Triton X‐100, 0.1% sodium dodecyl sulfate, 50 mmol/L Tris‐HCl, pH 7.4, 150 mmol/L NaCl, 1 mmol/L EDTA, 1 mmol/L EGTA, 10 mmol/L β‐glycerol‐phosphate, 10 mmol/L NaF, and 1 mmol/L sodium orthovanadate) containing a protease inhibitor cocktail (Roche Applied Sciences). Proteins were separated by sodium dodecyl sulfate–polyacrylamide gel electrophoresis and then transferred onto membranes, which were then incubated with the indicated primary and secondary antibodies. Chemiluminescence was detected using an enhanced chemiluminescence plus reagent (GE Healthcare Biosciences).
Phospho‐receptor tyrosine kinase arrays were performed using a phospho‐receptor tyrosine kinase array kit (R&D Systems) in accordance with the manufacturer's instructions. Bands and dots were detected using the ImageQuant LAS‐4000 imager (GE Healthcare Biosciences).

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.
