Normal Chicken 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  

High Quality and Safety Standards

Our Normal Chicken Serum is produced following stringent quality controls, including sterile filtration and negative mycoplasma testing, to ensure optimal purity and reliability. Each batch exceeds 99% purity and is carefully examined for endotoxin, maintaining levels under 1 EU/mL. The serum comes in aseptic, tamper-evident bottles to guarantee integrity during handling and usage.


Versatile Research Applications

This serum is widely used as a blocking agent in immunoassays, including ELISA and Western blotting. It effectively minimizes non-specific binding, thereby improving assay precision and reproducibility. Its characteristic properties also make it suitable for use in tissue culture and other research protocols requiring a reliable control serum.
