Product Information
The tumor suppressor p14ARF is widely deregulated in many types of cancers and is believed to function as a failsafe mechanism, inhibiting proliferation and inducing apoptosis as cellular response to a high oncogene load. A 22-amino-acid-long peptide derived from the N-terminal part of p14ARF, denoted ARF(1–22), which has been shown to mimic the function of p14ARF, has cell-penetrating properties. This peptide is internalized to the same extent as the cell-penetrating peptide (CPP) TP10 and dose-dependently decreases proliferation in MCF-7 and MDA MB 231 cells. Uptake of the ARF(1–22) peptide is associated with low membrane disturbance, measured by deoxyglucose and lactate dehydrogenase (LDH) leakage, as compared to its scrambled peptide. Also, flow cytometric analysis of annexin V/propidium iodide (PI) binding and Hoechst staining of nuclei suggest that ARF(1–22) induces apoptosis, whereas scrambled or inverted peptide sequences have no effect. The ARF(1–22) peptide mainly translocates cells through endocytosis, and is found intact inside cells for at least 3 hours.

| About TFA salt: | Trifluoroacetic acid (TFA) is a strong acid, which is commonly used to cleave synthesized peptides from solid-phase resins and is also used to improve HPLC performance in the peptide purification step. By default, custom peptides are delivered as lyophilized TFA salts, and can contain as much as 10-45% TFA. TFA in custom peptides can cause inexplicable discrepancies in subsequent assay data. For instance, TFA in nM concentrations has been shown to interfere with cellular assays, inhibiting cellular proliferation in some instances, and increasing cell viability in others. It has also been found to be an unintended allosteric modulator of the glycine receptor, GlyR. TFA Removal Service is recommended for: > Peptides that will be used in cellular assays > Peptides that will be used as APIs or in manufactured products > For hydrophilic peptides containing numerous basic residues |
