General description

Protein Extraction Reagent Type 4, is a highly premixed, prequalified and effective protein solubilization and extraction reagent composed of urea, thiourea, Trizma®, and detergent C7BzO (C0856).


Protein extraction reagent type 4 is optimized for proteomic studies. Cellular and organelle membrane solubilizing reagent is ideal for protein extraction prior to isoelectric focusing and 2D electrophoresis. Reducing and alkylating reagents TBP (T7567) and iodoacetamide (A3221) are recommended for use with this reagent. Protein extraction reagent type 4 is also available as a component of the ProteoPrep® Sample.


4 bottles in poly bottle


Contains urea, thiourea, Trizma®, and detergent C7BzO (C0856).
