Frequently Asked Questions (FAQs)
- What is the purity of gelatin products?
We do not determine the purity of fibronectin solutions. All our fibronectin powders are 70 - 90% pure.
- What is the best solvent to dilute gelatin powders?
The solvents that are compatible to dilute gelatins are provided in Table 1
- How long can gelatin be stored?
Gelatin solutions can be stored indefinitely at 2 - 8 °C. Gelatin-coated plates can be stored at 2 - 8 °C for up to 4 weeks provided they are sealed well to prevent contamination and/or over-drying up of gelatin. Do not use the product if discoloration or cracks appear on the surface of the coated material.
- What is the significance of Bloom number for gelatins?
Bloom number was introduced by Oscar T. Bloom and indicates the stiffness of a gelatin film. It was first measured using a Bloom Gelometer by a controlled process to measure the rigidity of a gelatin film. A higher number indicates a stiffer product. The Bloom number/Bloom strength helps in choosing the right gelatin product for your applications.
