Cathelicidins are a class of gene-encoded immune effectors in vertebrate innate immune system. Ps-CATH4 is a novel cathelicidin which was found in Chinese soft-shell turtle (Pelodiscus sinensis). Ps-CATH4 was expressed in lung, spleen, liver, kidney, muscle, stomach and intestine. Ps-CATH4 showed the most potent and broad-spectrum antimicrobial activities against the tested pathogens, with the MICs mainly ranging from 2.34 μg/ml to 18.75 μg/ml. Ps-CATH6 showed relatively low antimicrobial activity. Ps-CATH4 and 6 showed relatively low cytotoxicity towards RAW264.7 cells, inducing 15.95% and 10.98% cell death, respectively. Ps-CATH4 showed more potent membrane permeabilization effect than Ps-CATH6, which is consistent with their different antimicrobial activities.

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 |
