The standardized protocol [24] was adopted for Western Blotting. Specific primary antibodies- Syp (Santa Cruz Biotechnology. sc9116); PSD95 (Pierce Biotechnology, Inc. MA1045) and loading control (GAPDH & β actin; Bioss, USA) in dilutions of 1:1000 were used for primary incubation followed by overnight incubation with secondary antibody (Goat anti mouse sc 2005 or Goat anti rabbit sc 2004, SantaCruz Biotechnology; dilution- 1:2000). Bands were visualized using DAB. The blots were scanned for densitometric analysis using Quantity 1 software of Gel Documentation System (Bio-Rad, USA). The result was expressed as change in terms of control as follows: ODPE/ODLEODPC/ODLC where, ODPE, LE, PC, LC referred to OD of experimental group, loading control in experimental group; control group; loading control in control group respectively.

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.
