Normal Goat Serum

About Normal Goat Serum

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 

Optimized for Immunostaining Needs

Normal Goat Serum is meticulously processed and sterile-filtered to offer superior performance as a blocking agent in immunohistochemistry and immunofluorescence. With over 98% purity and no added preservatives, it significantly reduces non-specific binding, ensuring clearer and more reliable experimental results for research and laboratory professionals.
