Included in every package
How pure the Capreomycin sulfate is and how much is in the vial: purity in area percent, quantity in mg per vial against the label. Details
Included in every package
Whether the sample contains Capreomycin sulfate, compared with a reference standard. Reported as match or no match. Details
Quoted
Whether the molecular mass matches Capreomycin sulfate, which helps catch look-alike products. Details

Identity: Capreomycin sulfate (mixture of capreomycins IA, IB, IIA and IIB)
Identity, purity and quantity are measured on the lab’s peptide method: reversed-phase HPLC on a C18 column with a water and acetonitrile gradient containing 0.1% TFA, UV detection at 214 to 220 nm, and LC-MS intact mass for identity, against a reference standard.
Testing to the USP Capreomycin Sulfate monograph is available and quoted for these tests: identity by HPLC retention time against a reference standard and LC-MS intact mass, purity and assay by HPLC with UV detection, and related compounds by HPLC.
Send 1 vial for Level 1 Silver, 3 vials for Level 2 Gold or 4 vials for Level 3 Elite; raw powder purity needs a 50 mg sample. Results arrive in 3 to 5 business days; sterility takes 14 days.
No. The $250 test covers identity, purity and quantity by HPLC and LC-MS against a reference standard. Testing to the USP Capreomycin Sulfate monograph covers the monograph tests listed on this page and is quoted.
Capreomycin is a mixture of closely related cyclic peptides, mainly capreomycins IA and IB. HPLC separates the components, and LC-MS confirms their masses.
No. Potency in units is a separate microbiological measurement and is not part of the $250 test, which gives the component makeup and chemical purity.
