Gibco™ Fetal Bovine Serum, dialyzed, US origin

Description
Gibco Fetal bovine sera include a broad range of specialty sera, earning the trust of researchers with consistent quality and award-winning support that helps meet your unique research requirements. Dialyzed FBS provides a more controlled and defined environment with the removal of small molecules, enhancing outcome accuracy and reliability.

Frequently Asked Questions (FAQs)
- Heating inactivates complement. Active complement can participate in cytolytic events, contract smooth muscle, release histamine from mast cells and platelets, and activate lymphocytic and macrophage cells. Applications where heat-inactivated serum is recommended include immunological studies and culturing of embryonic stem cells (ESCs), insect cells, and smooth muscle cells.
- Heat inactivation helps to achieve bottle-to-bottle and lot-to-lot stability by neutralizing many factors that can vary largely from lot to lot.
- There aren't necessarily disadvantages to heat inactivation of FBS, but there is some evidence that suggests there may be no added benefit to it unless you are carrying out immune studies.
Note: Heat inactivation is performed in a 56 degrees C water bath for 30 min with swirling every 10 min or so for heat distribution and to lower the degree of protein aggregation/flocculant precipitation. Note: If the time or temperature is exceeded, the serum may thicken to a gel. If this occurs, the serum is no longer usable. Unnecessary heat inactivation can take up time and potentially lead to wasted reagents if a mistake is made during the protocol1.

The raw serum is processed through a dialysis system that has a 10 kDa cutoff. Therefore, many proteins, peptides, as well as some hormones, glucose, amino acids, and other exogenous materials are removed.
Serum can be kept at 2-8 degrees C for up to 4 weeks.
Yes, we also offer a 10 X 50 mL package, which is equivalent to a 500 mL bottle of FBS.
Our previous One Shot bottle, a 60 mL Nalgene media bottle, is not designed for easy pipetting and pouring whereas the new One Shot FBS bottle has a propietary design that was developed specifically for FBS use. This design allows you to freeze, thaw and pour without the need to aliquot, which minimizes the amount of FBS handling and reduces the risk of contamination.
For research use or further manufacturing use only. Serum and blood proteins are not for direct administration into humans or animals.
