Comprehensive Protein Analysis Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cells were lysed in cell lysis buffer (Cell Signaling Technologies) containing protease inhibitor cocktail (Sigma-Aldrich) and phosphatase inhibitor cocktail 3 (Sigma-Aldrich), 10 mM NaF, and 1 mM phenylmethylsulfonyl fluoride (PMSF). Cell lysates were analyzed by a bicinchoninic acid (BCA) assay (Pierce) for protein quantification, and equal amounts of protein were loaded for SDS-PAGE. Immunoblotting was performed as described using the following specific antibodies: HA (BioLegend; catalog no. 901501), IκBα (Abnova; catalog no. MAB0057), p-IκBα and TRAF6 (Cell Signaling Technology; catalog nos. 9246S and 8028, respectively), p-p38 and p38 MAPK (Cell Signaling Technology; catalog nos. 4511T and 8690T, respectively), glyceraldehyde-3-phosphate dehydrogenase (GAPDH; Bio-Rad; catalog no. AHP1628), SAMHD1 (Abcam, catalog no. 67820, or ProSci; catalog no. 8007), TAB3 (Cell Signaling Technology; catalog no. 14241S), TAK1 (Cell Signaling Technology; catalog no. 5206S) and pTAK1 (Thr187) (Cell Signaling Technology; catalog no. 4536S), and Flag (Sigma; catalog no. F1804). Detection of GAPDH protein was used as a loading control. For densitometry, low-exposure images were analyzed using ImageJ or Image Studio Lite, and the signal for the target protein was normalized to that of GAPDH (17 (link)).

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.
