What researchers say about Pel-Freez
-
“Pel-Freez's IgG/IgM depleted human complement has been crucial for complement-dependent bactericidal assays in my lab. The material is of the highest quality, with minimal lot-to-lot variation. This reagent has saved us considerable time and expense.”
-
“The Ig-depleted normal human serum worked great in our SBAs, and being able to buy it in single-use 1 mL vials means we never lose complement activity to repeat freeze-thaw.”
-
“We screened several Pel-Freez depleted human complement lots for our gonococcal SBA work and found the lyophilised form perfectly reliable over time, with stable results weeks after reconstitution. The team's support in switching over to their product was wonderful.”
-
“Getting a rabbit serum sample shipped that quickly was fantastic. It has been a real struggle to source rabbit serum, and Pel-Freez came through.”
-
“Thank you for the eyes. They worked great, and we came back to order more freshly dissected rabbit eyes.”
