Products classified under HTS 3507.90.20.00
Penicillin G Amidase Enzyme Powder
Penicillin G amidase is a purified enzyme used in the biopharmaceutical industry to hydrolyze penicillin G into 6-aminopenicillanic acid (6-APA), a key intermediate for semi-synthetic antibiotics. This powder form is specifically classified under HTS 3507.90.20.00 as it matches the description of Penicillin G amidase, a prepared enzyme not elsewhere specified.
Recombinant Penicillin G Acylase Lyophilized
This lyophilized (freeze-dried) recombinant form of Penicillin G acylase, produced via E. coli expression, is used for industrial biotransformation of beta-lactam antibiotics. Classified under HTS 3507.90.20.00 due to its specific identity as Penicillin G amidase, excluded from other chapters per notes.
Penicillin G Amidase 100,000 U/g Preparation
A high-activity (100,000 units per gram) preparation of Penicillin G amidase in stabilized powder form for large-scale fermentation processes in antibiotic production. HTS 3507.90.20.00 applies specifically to this named enzyme, distinct from general dextrins or hardened proteins per chapter exclusions.
Immobilized Penicillin G Amidase Beads
Penicillin G amidase immobilized on agarose or silica beads for continuous flow biocatalysis in pharmaceutical manufacturing. Still classified under HTS 3507.90.20.00 as the principal enzyme is specifically Penicillin G amidase, not reclassified by immobilization.
PenG Amidase Solution 50% Glycerol Stabilized
Liquid formulation of Penicillin G amidase stabilized in 50% glycerol for cold storage and easy dispensing in lab-scale antibiotic synthesis. HTS 3507.90.20.00 covers this specific amidase preparation, excluded from Chapter 34 washing preps or Chapter 30 medicaments.
