Peritubular myoid (PTM) human cells can be tagged with proteins such as :

• ACTA2 -at any stage of maturity-
• COUP-TFII -for the immature stage; as well as Leydig cell expression-
• AR -for the mature stage-

Do you know antibody(ies) that can specifically target(s) a protein(s) expressed only in immature PTM cells?

Thank you in advance.

Best regards,
