Select this product for Molecular Innovations name, COVID-19 Convalescent Patient Antibody, IgG Fraction and product number, COVID-GF.

Human IgG from Covid-19 Convalescent Plasma Fractionated Purified Lyophilized from Innovative Research has been purified by immobilized Protein A from pooled sera collected from convalescent COVID-19 patients. This is a Lyophilized powder buffered in 0.05M Sodium Phosphate; 0.1M NaCl; 1mM EDTA; pH 6.6.

Serum used for this antibody fraction was collected from COVID-19 convalescent patients at least two weeks after symptom onset. Positive COVID-19 status was confirmed via PCR test and serology antibody test. This preparation contains the full IgG fraction of the serum, including antibodies of isotype IgG directed against SARS-CoV-2.

More Details:

• Species: Human
• Target:Antibodies of isotype IgG
• Purification Method: IgG Fractionated
• Source: Human serum

Additional Information:

This product can be used as an postive control or calibrator in variety of serological assays. It can also be used in a wide range of in vitro research applications. At Innovative Research, we provide reliable, consistent products that deliver reliable, consistent results.

• Preheat a water bath to 37 C.
• Place the frozen plasma sample directly in the water bath.
• Gently agitate the plasma sample every 5-10 minutes to insure even thawing.
• The total thawing time will depend on the frozen sample volume. A 10 ml sample might be thawed completely in 5 minutes, but a large sample could take up to 1 hour.
• The thawed sample should be used immediately or stored at 4 C for up to 24 hours. Liquid plasma should never be kept on ice or stored below 0 C as the cold may cause clotting.
• Plasma should be visually inspected for signs of clotting or precipitation before use in experiments. A coagulation test such as aPTT can also be performed to verify the preservation of the hemostasis system.
• Plasma should always be snap-frozen by placing the tube in dry ice for at least 1 hour. Large containers can be covered in dry ice for even freezing.
• Frozen plasma should be stored at –20 C or colder. Lower temperatures will help preserve labile plasma proteins for longer time periods.
