Suspension Reagent to remove Hemoglobin interference for PCR
Some infectious viruses are known or suspected to be associated with red cells, such as Zika and West Nile viruses. So to detect their presence, it is becoming increasingly apparent to use whole blood, rather than plasma alone, as a starting sample type. However, the presence of hemoglobin from whole blood lysates is challenging for PCR because of the large amount of hemoglobin present. HemogloBind™ Nucleic Acid is designed to efficiently remove hemoglobin while maintaining very high recovery of nucleic acids, both RNA and DNA.
The protocol is easily scaled up or down to accommodate different starting blood volumes and works with common lysis buffers. Simply adjust the reagent volumes 5:1 proportionally to the starting blood volume.
