Turkish Airlines Miles&Smiles - Receiving BP at TK lounge in IST

I will be arriving in IST with TK business Class and my connecting flight is also with TK.
I know that i can get my BP at the business class lounge in case i did not receive my BP earlier.
But i believe that you need an valid BP to go up the escalator to the departure hall.
Can i also use my ticket to go up the escalator ?
I would like to avoid the transit desk as this is an madhouse for most of the time.

Sorry but you can't get to the floor up without a BP. If you did get it issued at origin, you'll have to queue at the transit desk. No other option...
