Description

TAT peptide (TFA) is a cell penetrating peptide (GRKKRRQRRRPQ) derived from the trans-activating transcriptional activator (Tat) from HIV-1[1][2].

IC50 & Target

HIV-1

 

In Vitro

TAT peptide (TFA) is a cell penetrating peptide (GRKKRRQRRRPQ) derived from the trans-activating transcriptional activator (Tat) from HIV-1[1]. TAT peptide (TFA) (GRKKRRQRRRPQ) functionalized hybrid nanoparticles are also studied due to their combined magnetic enrichment and optical detection for cell separation and rapid cell labelling. A cell viability assay reveals good biocompatibility of these hybrid nanoparticles[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
