Jimena,
If you are just working with antibody, and nothing else, or discarding unused antibody it might be a straight forward answer.
Usually antibody work involves cells and other reagents, so perhaps those material are hazardous or biohazardous and need to be handled by RCRA or State Regulated Medical Waste rules.

Antibodies by themselves are not RCRA hazardous, they are made of amino acids. That being said, if they are used with cells that are RG2 organism or higher or of human origin, you might want to consider managing wastes as a regulated medical waste.

Other factors you may want to consider is the type of lab environment, is this a teaching/learning environment or is it institutional research or some commercial operation. It sounds like you might be using a good deal of single use plastic, perhaps switching to glass tubes, plates, and autoclaving tips to be reused, might cut down on the need to dispose these items.

There is usually a struggle discarding things that look like medical waste, but are not hazardous or infections, into regular trash. If this is the case, maybe training your lab and housekeeping staff can solve some problems. There are pro's and cons to single use plastics, and switching to reusable labware like we used to have can be a chanllenge.
Good luck, and I hope you figure it out and let us know if you have any success.
James

Hello Everyone,

I wonder if anyone can give me an insight on good practices of antibody related materials disposal, and anything that has/potentially has contacted such materials (pipette tips, gloves, vials, tubes, etc.). Can this waste be discarded into regular trash.

Thank you,
Jimena Luna
