All our products listed in this catalog are tested rigorously by our quality control department. The purity of the products is guaranteed according to the following criteria.
Amino Acids, peptidyl Enzyme-Substrates and Peptide Derivatives of the 3000 Series:
The following letters are used to designate the different guarantee standards:
AA: A mono-spot is detectable by TLC when 100 microgram is applied to the plate. The amount of contamination detectable by HPLC is less than 1%.
A: A trace of impurity might be detectable by TLC when 100 microgram is applied to the plate. The amount of contamination detectable by HPLC is less than 2%.
B: Contamination of less than 4% might be detectable by HPLC.
A-B: This compound is synthesized as material of grade A, but may gradually decompose to grade B within one year, even under cold storage conditions.
Biologically Active Peptides of the 4000 Series:
All these peptides are chemically synthesized using carefully selected starting materials, and strictly purified to show a single TLC spot in two different solvent systems upon application of 50 microgram. Nevertheless, several minor spots are detectable on TLC with Met-containing peptides since they may be easily oxidized to Met-sulfoxide even during analysis. Impurities detectable by ordinary gradient HPLC systems are less than 1% with almost all of our peptides, except Met-containing peptides. The peptides which are followed by the words “Purity Information” and letter symbols, such as “Purity Information: QP See page III”, can be explained as follows:
QP: These compounds have some inherent instability. During storage, even under freezer conditions, a trace of impurity may become visible by TLC analysis. The amount of impurity determined by HPLC is less than 1%.
QE: These compounds have some inherent instability. Their purity is guaranteed to be higher than 97% by HPLC.
QX: The purity of these compounds is guaranteed to be higher than 97% by HPLC.
QZ: The purity of these compounds is guaranteed to be higher than 95% by HPLC.
These enzymes listed in this catalog are supplied by various manufacturers, who are responsible for their specifications.
Bacterial Enzyme Inhibitors
Almost all enzyme inhibitors listed in this catalog are isolated from cultured media of microorganisms. Many of these compounds are too inherently unstable to allow for high standards of purity. The homogeneity of these compounds cannot be guaranteed except for their specific inhibitory activities; data are available on request.
Our peptide antisera are sold in vials as amorphous powders obtained after lyophilization from 0.001 M phosphate buffer (pH 7.0). The specificity and sensitivity are determined by the enzyme immunoassay technique; data are given on a data sheet accompanying each vial.
