Yes, you are right. The number after the dash signifies when the lot was aliquoted. If the number directly after the "GR" is the same then it is the same lot.

For ab19483, chicken polyclonal to Protein A, we have 16 vials of lot GR58389-4 in our US office ready to ship and an additional 30 units of lots GR58389-3 and GR58389-4 in our UK office.

For ab18596, chicken polyclonal to Protein A (HRP), we have 1 vial of GR74278-4 in our UK office which would take a few extra days to ship to you. We have two new lots in for that antibody, but only 1 vial left of the lot you requested.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Thank you for contacting us.

We currently have x vials of ab19483, lot GR58389 worldwide (x in UK office, x in US office, x in Japan office.)

For ab18596, we only have 1 vial of lot GR74278 in stock, however we do hold 8 other vials of different stocks of this antibody in the UK.

The way we number our lots is indeed the way you mentioned. The first part of the lot number e.g GR12345 corresponds to one particular lot. The last number e.g GR12345-X corresponds to the a particular date where we receieved the antibody from our labs. This means that lots GR12345-1 and GR12345-2 of a particularly antibody originate from the same stock but were delivered to our stock rooms at different days therefore these should be identical.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

I appreciate your cooperation and understand your concerns. It is regrettable the results from lot 793467have not been assatisfactory for the customer. I can confirm that ab18596 and ab18596-1 are the same antibody. The -1 just relates to the size.

(I assume there was a typing error in your email, ab18596 and ab18569-1 are not the same antibody).
