Characterization of LA/TCS@PLGA-NP Protein by SDS-PAGE

Check if the same lab product or an alternative is used in the 5 most similar protocols
The LA/TCS@PLGA-NP protein was characterized by SDS–PAGE. The envelope proteins of L. acidophilus, L. acidophilus envelope fragments and LA/TCS@PLGA-NPs were extracted by cell total protein extraction kits (Beyotime). The extracted proteins were run on a 12% SDS–PAGE gel in running buffer using a BIO-RAD electrophoresis system at 70 V for 0.5 h and then at 140 V for 1 h. Finally, the SDS–PAGE gel was stained with SimplyBlue for visualization.
The LA/TCS@PLGA-NP protein was further detected by quantitative analysis according to Feng et al. [58 (link)]. The LA/TCS@PLGA-NPs were lyophilized and weighed. The protein content of LA/TCS@PLGA-NPs was measured by a BCA protein assay kit. The protein loading yield, which is defined as the weight ratio of immobilized proteins on the nanoparticles, was calculated.

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.
