Storage & Sensitivity
Keep Cold.

Citrate, is used as an anticoagulant and also used as a biological buffer. It is often used to prepare sodium citrate buffer for antigen retrieval of tissue samples. The citrate solution is designed to break protein cross-links, thus, unmasking antigens and epitopes in formalin-fixed and paraffin embedded tissue sections, resulting in enhancing staining intensity of antibodies. Citrate has anticoagulant activity and as a calcium chelator, it forms complexes that disrupt the tendency of blood to clot.


Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Keep away from strong oxidizing agents.
