Hunky Protein Stability and Aggregation Platform
Automated detailed protein stability platform
Knowledge of the stability of your protein formulation is extremely important. Small adjustments to your formulation can have a drastic effect on the overall stability. This is where Hunky provides direct assistance by determining the ?G information that other systems cant provide. This data will quantify when your protein will aggregate.
Hunky can measure up to 96 samples at once and features 4 apps to suit your specific application, automated liquid handling and full data analysis making it the must have instrument for protein stability determination.
What doe Hunky Measure?
Hunky provides a comprehensive quantification of protein stability by measuring:
- C½ rank stability
- ?G quantify stability
- Agg Path predict aggregation
- ?Gtrend zoom in on aggregation
Why is ?G So Important
Biologics can exist anywhere between their native (folded) state and their denatured state. High ?G values indicate stable formulations. If your formulation is highly denatured it will have a low ?G, it could be very unstable and not worth pursuing.
?G provides a detailed differentiation of protein formulations that would otherwise be too difficult to determine using Tm alone.
Denaturation Curves
Hunky also produces denaturation curves and calculates C½, the concentration of denaturant required to unfold half your protein.
By combining C½ and Tm data you can double-check your results and easily determine which formulations are worth pursuing.
Quantify How Denatured Your Protein is
The ?G values that Hunky produces give you a direct indication of how much denatured protein you have in your sample.
Automated data fitting shows you up to 3 unfolding transitions, revealing small differences in your proteins stability. All these experiments are carried out at room temperature to remove temperature differences from the equation.
Aggregation Propensity
Agg Path is a measure of aggregation propensity. Hunky measures ?G at one high and one low concentration. By identifying at the formulation where ?G stays constant, youll know you are on a winner.
?Gtrend provides an even more detailed method to assess aggregation propensity by looking at how ?G changes as a function concentration giving you a fantastic insight into whether your formulation will aggregate, how it will aggregate and how much it could aggregate.
