Gibco® horse serum is donor-herd collected, processed, and manufactured in New Zealand. Each lot of horse serum is tested for its ability to support the growth of Sp2/O-Ag14 (murine myeloma) cells in control medium containing the test lot of serum. Results are compared to parallel results obtained using control growth medium containing a previously characterized reference serum.

  • EIA (Equine Infectious Anemia) tested

Horse serum is available in both a heat inactivated and non-heat inactivated format.  HI serum is heated for 30 minutes at 56°C while mixing to inactivate the complement.
