"TC Supernatant" vs. "Purified"

TC Supernatant
Hybridoma tissue-culture supernatant (5mL) generally containing 10-50 ug/mL monoclonal antibody (clone-dependent) can be a very economical choice. Supernatant is suitable for most applications including Western Blot, immunocytochemistry, immunohistochemistry etc. For applications requiring higher antibody concentration or purity (such as immunoprecipitation, microinjection, or conjugation) it is recommended that you purchase the purified form of the antibody (supplied at 1mg/mL).

Purified mAbs
Produced by in vitro bioreactor culture of hybridoma lines followed by Protein A affinity chromatography. Purified mAbs are >90% specific antibody at 1mg/mL.
