In January of 2020, Abcam acquired an experienced cell-engineering team from ASC to form the core engine of our in-house gene-editing capability, along with the AccuRef reference standards product line. We continue to actively invest in these and are pleased to announce that the team is moving to a new state-of-the-art facility, increasing our dedicated facility square footage by over 300%.

Our commitment to quality requires that we enforce a pause in production and shipping of the AccuRef standards range until all the necessary systems and processes are in place, and tested, in our new facility. This pause is scheduled to be for 12 weeks from 1st December 2020.

After this period, we anticipate our standard order fulfilment lead time will be in the order of 8-12 weeks. We appreciate that this might cause some disruption to a number of customers and if you are concerned please do contact us on

Custom Services


Our Onco-Ref™ Custom FFPE Cell Block Services gives you the flexibilty to receive a custom FFPE product with high quality and consistency with a fast turnaround time at a great price. Simply ship us your cells. If needed, we can culture, fix the cells using buffered formalin (10% for 24hrs at room temperature, typically), and then prepare a cell core and embed the core into a paraffin block. If requested (optional), we can prepare FFPE Cell slides or FPPE Cell scrolls from a freshly prepared FFPE Cell Block. We typically turnaround a FFPE Cell block in 7 working days from receipt of 1 x 108 cells.
