Penta lysine

Penta lysine is an antimicrobial peptide. Penta lysine inhibits the growth of Gram-positive bacteria (including methicillin-resistant Staphylococcus aureus and Bacillus subtilis) as well as Gram-negative bacteria (including Escherichia coli, Acinetobacter baumannii and Pseudomonas aeruginosa). Penta lysine induces hemolysis in human red blood cells. Penta lysine can be used in the research of bacterial infections (including MRSA and Pseudomonas aeruginosa infections).

For research use only. We do not sell to patients.

Biological Activity

Description

In Vitro

Penta lysine (LLLLL) (0.0625-128 μg/mL; 16 h) inhibits growth of E. coli, A. baumannii, P. aeruginosa, S. aureus, MRSA, and B. subtilis with MIC values ranging from 2.3 μM (MRSA) to 36 μM (A. baumannii)^[1].
Penta lysine (142 μM) induces 6.9% hemolysis of human red blood cells at 142 μM^[1].
Penta lysine has an apparent lipophilicity corresponding to a retention time of 19.1 min on a reversed-phase C₁₈ HPLC column^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
