pNA Substrates for Elastase Now Available from Peptides International

New pNA Substrates for Elastase
Now Available from Peptides International

Synthetic enzyme substrates are generally divided into chromogenic and fluorogenic substrates. With chromogenic compounds, such as pNA-containing peptide substrates, rates of hydrolysis upon cleavage are measured in continuous or stopped assays in a spectrophotometer. Rates of hydrolysis of fluorogenic compounds, such as MCA substrates, are measured in continuous or stopped assays in a spectrofluorometer.

These substrates for elastase are now available from Peptides International. For a listing of related substrates please visit our pNA substrate link.
