Western Blotting Protein Detection Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
Western blots were performed as previously described (49 (link)). In brief, protein lysates from cell culture or tumor tissues were extracted in ice-cold RIPA buffer (50 mM Tris-Cl, 150 mM NaCl, 1% NP-40, 0.5% sodium deoxycholate, 0.1% SDS) containing cocktails of protease (Thermo Scientific) and phosphatase inhibitors (Sigma-Aldrich), by centrifugation (13000g, 15 min) at 4°C following 3 freeze-thaw cycles. Proteins were separated by SDS-PAGE and transferred to methanol activated polyvinylidene difluoride (PVDF) membrane (VWR). The primary antibodies used include the following: rabbit anti-mouse Fbln5 (1:1000), rabbit anti-human Fbln5 (1:500) (HPA000868, Sigma Aldrich), anti-Nqo1 (1:1000) (ab34173, Abcam), anti-α-Tubulin (1:1000) (ab4047, Abcam) and anti-β-actin (1:5000) (A2066, Sigma-Aldrich). HRP-conjugated donkey anti-rabbit IgG (1:10000) (Jackson Immunoresearch) as secondary antibodies were used.

Western Blot Analysis of DKK1 in Aged Rats

Check if the same lab product or an alternative is used in the 5 most similar protocols
Protein from aged rat lysates ± RLX (n = 3/group) was separated using pre-cast Mini-PROTEAN TGX 7.5% polyacrylamide gels and transferred to a PVDF membrane. Membranes were then probed for mouse anti-DKK1 (1:500, Santa Cruz sc374574) and rabbit anti-α-tubulin (1:1000, Abcam, ab4047). Membranes were developed using Pierce ECL Western Blotting Substrate (ThermoScientific, #32109) according to manufacturer instructions and developed by autoradiography. Quantification of the optical density of DKK1 or tubulin bands were performed using ImageJ software and DKK1 expression was normalized to α-tubulin.

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.
