Each test can be added to a package or ordered on its own. Results arrive in 3 to 5 business days.
Included in every package
How pure the MIF-1 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 MIF-1, compared with a reference standard. Reported as match or no match. Details
Quoted
Whether the molecular mass matches MIF-1, which helps catch look-alike products. Details

MIF-1 runs on the lab’s peptide purity and quantity method: reversed-phase HPLC on a C18 column with a water and acetonitrile gradient containing 0.1% TFA, and UV detection at 214 to 220 nm. Purity is the main peak’s share of the total peak area, quantity is measured against a reference standard, and identity is confirmed by retention time and UV spectrum against the same standard. LC-MS confirmation of the mass is quoted separately.
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.
By HPLC with UV detection at a low wavelength against a reference standard, on a method that keeps this early-eluting peptide retained.
Quantity is reported as peptide in mg per vial. Acetate or TFA counterions add weight to the powder but not to the peptide result; the counterion test ($70) measures them.
