Name: Anti-Human IgG (Fc-Specific, Peroxidase-Conjugated)
Form: Liquid, clear to slightly yellow solution
Type: Immunological laboratory reagent, antibody conjugate with horseradish peroxidase
Main Use: Binds to human IgG Fc regions in biochemical or diagnostic assays, especially ELISAs and immunoblots
Key Components: Antibody proteins, stabilizing agents, trace amounts of preservative (often thimerosal or similar)
Label Elements: Laboratory reagent; Not intended for therapeutic or diagnostic use in humans or animals
Potential Hazards: Irritation to eyes, skin, mucosa; Respiratory irritation with prolonged contact; Sensitization possible due to proteinaceous nature
Chronic Effects: Allergic reactions possible with repeated exposure; Splashes present a direct risk to eyes and oral mucosa
Pictograms: Exclamation mark (for irritant)
Active Ingredient: Anti-human IgG antibody, subclass and species dependent
Conjugate: Horseradish peroxidase enzyme bound to Fc-specific IgG
Buffer: Phosphate buffered saline, commonly with stabilizers such as BSA (bovine serum albumin)
Preservative: Thimerosal, sodium azide, or other antimicrobial agents at very low concentration
Protein Concentration: Varies, typically milligram per milliliter range
Eye Contact: Rinse eyes promptly with water for fifteen minutes; seek medical help if irritation continues
Skin Contact: Wash exposed area thoroughly with soap and water; remove contaminated clothing
Inhalation: Move to fresh air if aerosol or mist inhaled; seek medical attention if symptoms persist
Ingestion: Rinse mouth well; seek medical advice; do not induce vomiting except by explicit instruction of medical personnel
Suitable Extinguishing Media: Water spray, carbon dioxide, dry chemical, foam – selection based on surrounding materials
Hazardous Combustion Products: Carbon oxides, nitrogen oxides, sulfur oxides from preservative combustion
Protective Equipment: Firefighters benefit from self-contained breathing apparatus and protective gear
Fire/Explosion Risk: Solution form; not flammable, but dried residues or packaging may contribute to fire load
Personal Precautions: Wear gloves, goggles, and lab coat; avoid direct contact and prevent inhalation of vapors or droplets
Spill Procedures: Absorb with inert material such as paper towel or vermiculite; wipe surface thoroughly with detergent and water
Environmental Precautions: Keep reagent away from uncontrolled drains, surface waters, and soil; some preservatives (such as azide) impact aquatic organisms
Disposal: Gather waste in a sealed biohazard bag or chemical waste container for proper disposal
Handling: Keep container closed; use in well-ventilated areas; avoid aerosol generation and splashes
Storage Conditions: Refrigerate at 2–8°C; protect from light and temperature extremes; prevent freezing unless specified by supplier
Incompatibilities: Strong oxidizers, acids, or bases
Storage Life: Depends on preservative and manufacturer’s instructions, but frequent opening shortens viability
Engineering Controls: Work inside chemical fume hood or designated biosafety cabinet if possible
Personal Protection: Chemical-resistant gloves, splash goggles, laboratory coat
Hygiene: Avoid eating or drinking in laboratory; wash hands after use; promptly change contaminated clothing
Monitoring: No established occupational exposure limits; treat as a potentially infectious/proteinaceous biological sample
Appearance: Clear to yellowish liquid
Odor: Faint, protein solution smell – typically masked by dilute preservative
pH: Usually near neutral (6.5–7.5), depending on buffer composition
Boiling Point: Not applicable in normal use, as solution is stable at room and refrigeration temperatures
Solubility: Completely soluble in water
Viscosity: Comparable to other protein solutions
Stability on Standing: Long-term storage causes gradual denaturation or precipitation
Thermal Stability: Solution stable if refrigerated; degrades if frozen, heated, or exposed to direct sunlight
Reactivity: Not reactive under normal conditions; sensitive to oxidizing agents and acids
Decomposition Products: Protein denaturation products, low-level formaldehyde from thimerosal breakdown, nitrogen oxides
Incompatibility: Avoid mixing with other chemicals unless compatibility confirmed for assay purposes
Routes of Entry: Skin, eye, inhalation, accidental ingestion
Local Effects: May cause skin/eye irritation or allergic reactions
Acute Toxicity: Low toxicity under intended use; preservatives at low amounts, but sodium azide or thimerosal produce disproportionate effects if concentrated
Chronic Exposure: Repeated skin contact increases risk of sensitization or dermatitis
Carcinogenicity: Components not listed as carcinogenic in IARC or ACGIH tables at these levels
Persistence/Biodegradability: Protein fraction biodegradable; preservatives degrade slowly, may persist in aquatic environment
Toxicity to Organisms: Sodium azide and thimerosal both toxic to aquatic life; even very low concentrations affect fish and invertebrates
Mobility: Solution disperses rapidly in water, risk for sewage treatment disruption if discarded improperly
Bioaccumulation: Not expected for protein components, possible accumulation for organomercurial or azide preservatives
Waste Disposal: Collect all waste in designated hazardous chemical container; never pour down the drain
Decontamination: Surface spills decontaminated with dilute bleach solution, followed by detergent wash
Incineration: Preferred disposal method in accordance with local, state, federal rules for biohazardous and chemical waste
Classification: Not regulated for ground transport as a hazardous material at laboratory volumes
Packaging: Use robust, leak-proof secondary containment; keep absorbent material inside shipping box
Temperature: Ship with cold packs or on dry ice where required; avoid freezing unless stability data supports
Labelling: Mark outer package with “Biological Substance, Category B” label if required by shipper or receiving country
Hazardous Chemical List: Contains small amounts of chemicals classified as hazardous by OSHA/GHS, primarily due to preservatives
Labelling Compliance: US, EU, and Asian standards expect product labels with warning and safety symbols
Restrictions: Not for in vivo human or animal use; research only
Worker Protection: Follow established laboratory safety protocols, including regular re-training and incident reporting
