Good morning! I'm interested to improve recovery of Leishmania parasites from conventional NNN cultures obtained from tegumentary samples. Based on this publication (http://www.ncbi.nlm.nih.gov/pubmed/22994895) I think supplementation with Alanine/proline can improve considerable isolation of promastigotes... did anybody tested it before? If not, can you suggest me a protocol for implement a pilot experiment using proline/alanine? I have L-alanine (A7627-100G) & L-proline (P0380-100G) and I'm planning to prepare solutions containing both aminoacids at different concentrations with the intention to supplement NNN cultures from the beginning or between days 3-5. Best regards!
