Hello, Kumar,

Hello, Kumar,

As you rihghtly  not it is very difficult to prepare 8% casin solution,
For that you need to have bit patience, you add  step by step and vortex properly intialy you take RT PBS and after some time you incubate at 37oC for some time and again vortex it properly

dear rajeshwari,

dear rajeshwari,

kindly suggest me what is RT PBS and i shall be thankfull to you for explaining the process in detail as i am inexperinced in this matter.

just tell me the way you dissolve it as all protocol tell it to incubate at 37 or 70 *C with megnatic stirer.

i am trying to dissolve it by periodically adding small amount of casein to hot pbs (50-70*C on magnetic stirrer) but after autoclaving all casein converts to insoluble pink clump.
