Products classified under HTS 3821.00.00.90
LB Agar Plates for Bacterial Culture
Pre-poured LB (Luria-Bertani) agar plates containing nutrients essential for the growth and maintenance of bacteria such as E. coli. These prepared culture media fall under HTS 3821.00.00.90 as they are specifically formulated for the development of micro-organisms in laboratory settings. The 'Other' subheading applies since they are not single-cell protein media.
DMEM Cell Culture Medium
Dulbecco's Modified Eagle Medium (DMEM) is a liquid basal medium enriched with amino acids, vitamins, and glucose for maintaining human and animal cell lines like HEK293 or fibroblasts. Classified under HTS 3821.00.00.90 for prepared media supporting animal cell development in biotech research. The powdered or liquid form is ready for direct use in incubators.
Murashige and Skoog (MS) Basal Medium
MS medium powder containing macro and micro-nutrients, vitamins, and myo-inositol for plant tissue culture, supporting callus formation and shoot regeneration. Falls under HTS 3821.00.00.90 as prepared media for plant cell development in vitro. Used widely in agriculture biotech for micropropagation.
RPMI-1640 Medium for Lymphocyte Culture
RPMI-1640 is a buffered liquid medium with HEPES, sodium bicarbonate, and L-glutamine optimized for human lymphocyte and hybridoma cell maintenance. HTS 3821.00.00.90 covers this as prepared media for human cell development in immunology research. Essential for monoclonal antibody production.
Bacto-Tryptone Soy Agar for Yeast Maintenance
Sterile Tryptic Soy Agar (TSA) plates with added yeast extract for maintaining yeast strains like Saccharomyces cerevisiae. Under HTS 3821.00.00.90 for micro-organism maintenance media. Used in brewing and biotech fermentation studies.
Fetal Bovine Serum Supplemented Medium
Basal medium kit with 10% fetal bovine serum (FBS) for serum-dependent animal cell lines like CHO cells. HTS 3821.00.00.90 applies to this complete prepared media for cell maintenance. Critical for biopharmaceutical protein expression.
Plant Preservation Tissue Culture Medium
Gelling medium with cytokinins and auxins for long-term plant cell line preservation at low temperatures. Classifies under HTS 3821.00.00.90 for plant cell maintenance media. Used for endangered species conservation.
