Normal Sheep Serum

Product Description

Normal serums are lipid extracted to improve clarity, dialyzed against phosphate buffered saline (PBS) containing sodium azide, and freeze dried. Normal serum diluted to 5% (v/v) in PBS is strongly recommended as a blocking reagent to reduce background from non-specific, conserved sequence and/or Fc receptor binding. Best results are obtained with diluted normal serum from the same host as the labeled antibody, as a separate incubation step before addition of the primary antibody.

Physical State: Freeze-dried solid 
Storage: Store freeze-dried powder at 2-8°C. When ready to use, rehydrate with indicated volume of d. water and centrifuge if not clear. Product is stable for about 6 weeks at 2-8°C as an undiluted liquid. Prepare working dilution fresh each day. For extended storage after rehydration, aliquot and freeze undiluted product at -20°C or below. Avoid repeated freezing and thawing. 

Expiration date: one year from date of rehydration. However, the expiration date may be extended if the product is stored according to the recommendation and the test results are acceptable for its intended use.

Preservative: 0.05% Sodium Azide  

Highly Pure, Sterile Serum for Research Applications

Normal Sheep Serum is trusted for its exceptional purity (>99%), sterile filtration, and low-endotoxin levels. It is especially beneficial in laboratory settings where contamination risks must be minimized, such as immunoassays, cell culture, and biotechnology research. Its sealed sterile vials ensure product integrity throughout storage and usage.


Convenient Sizing and Adaptability

To meet diverse laboratory needs, this serum is available in standard 10 mL, 50 mL, and 100 mL vials, as well as customizable volumes. This flexibility allows researchers to source the ideal amount for their experimental protocols, reducing waste and optimizing resource allocation.


Consistent Performance and Long Shelf Life

The serum maintains a stable pH (7.27.4) and clarity as a clear, odorless liquid, ensuring reproducible results. With an extended shelf life of up to 18 months when stored at -20C or lower, it offers lasting reliability for ongoing and future studies.
