iFormulate™, high throughput formulation development

iFormulate™ accelerates the development of biotech drugs. The iFormulate concept is based on an efficient high throughput algorithm that utilizes rational design of experiments and formulation parameters, to develop a pharmaceutically acceptable drug product.

Over the years we have helped our clients with the development of their protein drug candidate into stable drug products. We have developed high dose protein formulations and helped our clients overcome challenging formulation problems such as protein aggregation, and solubility problems.  Using the iFormulate platform, HTD Biosystems helps with rapid antibody screening and selection for the most stable formulations.


iFormulate™ was conceived for the purpose of providing the formulation scientist a predesigned formulation plate for assessing the stability of a protein drug using DOE (Design of Experiments) methodology. The basic plate consists of 20 unique formulations and 5 replicate formulations (for statistical data verification). The formulations are placed randomly to remove any bias. The DOE is a response-surface multivariate design that evaluates the effect of pH, ionic strength, buffer and stabilizer concentration on the protein of interest.
