HPLC or GC assay development, qualification, or validation
Residual solvent analysis
Development of LC- MS or LC-MS/MS assays for pharmacokinetic studies
ELISAs
Stability indicating method development
Stability testing of API or formulated products:
25°C, 60% R.H.
40°C, 75% R.H.
In vitro Testing
AllTranz has the ability to provide a number of in vitro tests to analyze the physicochemical properties of a compound.
In vitro drug permeation studies in flow through diffusion systems using cells either 1, 1.77, or 6.25 cm2 in diffusional area (special size requests considered).
Skin models:
Human skin (surgical waste or cadaver)
Hairless mouse
Rat
Guinea pig
Weanling pig or Yucatan pig
Polymeric membrane
Permeation studies using cultured human skin (EpiDerm) and tracheal/bronchial tissue (EpiAirway) to study: TEER, epithelial potential difference (PD), and TEWL.
In vivo Testing
AllTranz has a number of animal testing models for drug product evaluation following topical application, intranasal application, intravenous administration, and other routes of delivery:
Mice
Hairless rats and other rats
Hairless guinea pigs
Yucatan miniature pigs
Barrier function (irritation) studies can be determined by transepidermal water loss (TEWL), colorimeter and impedance.
