We normally only create technical notes about product availability when a product is on backorder. We did have inventory of the DY3174 kit (the human Myeloperoxidase DuoSet) last week but shipped the last kit in our stock on Friday. We have not yet received a backorder for this product, so no technical note has been created yet.
I checked with our kit planners and the lab is currently working on testing the next lot of this kit. Once testing is complete, it can be scheduled for packing. I would estimate that a new lot will likely be available within three weeks, but it could be sooner or later depending on the test results. The expiration date of the new lot would be May 2019, but this would only apply to the unopened kit. Once the kit has been opened and used, the reconstituted antibodies can only be stored for up to six months.
