TAT 2-4

TAT 2-4 (CPC catalog code TAT-003) is a synthetic cell-penetrating peptide (cpp) in the cell-penetrating category. It is provided as a lyophilized ~1 mg vial for in-vitro research use only.

Published and internal research programs use TAT 2-4 as a reference standard in cell-penetrating workflows — for example, intracellular cargo delivery (peptides, sirna, proteins) and endosomal-escape and trafficking studies. Human clinical evidence is not established.

No. TAT 2-4 is a research-grade reference peptide and is not approved by the FDA or any national regulator for human or veterinary therapeutic use. It is offered exclusively for in-vitro laboratory research and does not ship to the United States for consumer use.

In a cell-penetrating workflow, TAT 2-4 is reconstituted in sterile buffer or DMSO (solubility-dependent) and applied in the researcher's chosen assay format. Fluorescent-conjugate flow cytometry and confocal imaging are the standard uptake readouts.

Store lyophilized at −20 °C. Aliquot reconstituted stocks to avoid freeze–thaw damage. Follow your institution's standard operating procedures for handling synthetic peptides.

This kindr reference page mirrors CPC Scientific's catalog metadata for TAT-003. The upstream reference sheet — including sequence, purity, MW, and application notes where published — is linked from the buy panel. All orders placed on kindr Peptides ship internationally under research-use terms only.

Research-grade peptides in the CPC catalog are synthesized by solid-phase peptide synthesis (SPPS), purified by preparative RP-HPLC, and characterized by analytical HPLC and mass spectrometry. Typical purity is ≥95%; certificate of analysis is available on request.
