General description

Guanidine thiocyanate is a chaotropic agent that functions as a strong protein denaturant. It is widely used in RNA isolation protocols. Guanidine thiocyanate can irreversibly inactivate RNase and DNase and breaks cellular membranes. It dissolves proteins by disturbing their secondary structures. Guanidine thiocyanate also separates nucleoproteins from nucleic acids and aids the digestion of the proteins with proteases. It improves the activity of proteinase K thus making it the protease of choice.

Application

Guanidine thiocyanate solution has been used to extract:
  • plasma RNA from human immunodeficiency virus (HIV)-infected and control patients
  • total RNA from collected tissues (shoots, flowers, fruits, and seeds)
  • in reverse transcription-polymerase chain reaction (RT-PCR) analysis, RNA from teratocarcinoma cell line (Tera-1)

Disclaimer

possibly crystallized product can be dissolved again by slightly heating to 40-50 °C.

The parasitic flowering plant dwarf mistletoe (Arceuthobium spp., Viscaceae) is one of the most destructive forest pests, posing a major threat to numerous conifer species worldwide. Arceuthobium sichuanense (spruce dwarf mistletoe, SDM) infects Qinghai spruce (Picea crassifolia) and causes severe

Recent studies suggest that human endogenous retrovirus group K (HERV-K) provirus expression plays a role in the pathogenesis of HIV-1 infection. In particular, RNA from the HML-2 subgroup of HERV-K proviruses has been reported to be highly expressed at the

Human endogenous retrovirus (HERV-K (HML-2)) proviruses are among the few endogenous retroviral elements in the human genome that retain coding sequence. HML-2 expression has been widely associated with human disease states, including different types of cancers as well as with
