Do the recombinant laminins have any purification tag?
The α4 and α5 chains of our Biolaminin LN products (i.e. LN521, LN511, LN421, LN411) have a FLAG-tag at the N-terminal end. The α2 chain of LN211 has an HA-tag at the N-terminal end and a FLAG-tag at the C-terminal end. The LN111, LN121, LN221, and LN332 protein products do not contain any tags. Similarly, the Cell Therapy grade Biolaminin 521 (CT521) and the MX521 do not contain tags.
