Products classified under HTS 3002.12.00.20
Freeze-Dried Normal Human Blood Serum
Freeze-dried normal human blood serum is obtained from healthy human donors and processed to remove water while preserving proteins and antibodies. It falls under HTS 3002.12.00.20 as a normal human blood serum used in diagnostic assays, cell culture media, and research applications. This product is not modified for specific immunological purposes, distinguishing it from other antisera.
Liquid Normal Human Blood Serum for Cell Culture
Liquid normal human blood serum is pooled from screened donors and heat-inactivated for use in mammalian cell culture. Classified under HTS 3002.12.00.20 as unmodified normal human blood sera prepared for therapeutic, prophylactic, or diagnostic uses in research. It provides essential growth factors without specific immunological modifications.
Pooled Heat-Inactivated Human Blood Serum
Pooled heat-inactivated normal human blood serum is derived from multiple donors to ensure consistency for laboratory applications. It is classified in HTS 3002.12.00.20 as normal human blood sera, whether or not freeze-dried, due to its role in diagnostic testing and cell cultivation. Inactivation removes complement activity while retaining serum proteins.
Normal Human Serum AB Positive
Normal human serum AB positive is sourced from type AB donors, valued for low isoagglutinin levels in sensitive assays. Under HTS 3002.12.00.20, it qualifies as normal human blood sera for diagnostic and research uses without targeted modifications. Commonly used in blood banking and flow cytometry protocols.
Lyophilized Human Plasma Serum Pool
Lyophilized human plasma serum pool is freeze-dried normal serum from screened donors for long-term storage in labs. It fits HTS 3002.12.00.20 as normal human blood sera prepared for diagnostic purposes like ELISA blocking. Reconstitution yields standard serum properties.
