Fish Skin Gelatin

Many compounds have been added empirically to immunolabeling solutions for the purpose of minimizing background staining. Based on years of experience and controlled testing, Aurion has selected a group of compounds that are proven to be the most effective in their background reduction action. Researchers can obtain these items separately from Aurion and prepare blocking and incubation media to suit the needs of their own protocols.


The ready-to-use Blocking Solutions and the incubation media additive BSA-c™ are tuned for optimum background prevention and signal-to-noise ratio. In-depth information can be found in the respective product data sheets.

AURION also offers a number of components that allow researchers to formulate blocking, incubation and wash solutions according to the needs of their own experiments.

Product Description

The use of Cold Water Fish Skin Gelatin to prevent background reactions has been recommended by e.g. Behnke et al. (J. Cell Biol. 41, [1986], 386). The product is supplied as a liquid concentrate (40%).

As a rule the normal serum species should be the same as the secondary antibody species (e.g. use normal goat serum with goat-anti-rabbit conjugates).

Note: normal sera should not be used in combination with Protein A and Protein G gold reagents.


The products should be stored at 4-8°C.

Freezing is not recommended.
