Besides aptamers, we have some short single stranded DNA known as 'probes', which binds to other single stranded DNA. BBa_K3593006 is one of those so-called 'probes' in our design, and play important roles in our hardware, in which it binds and immobilizes the aptamer.  It has a strand consisting of a lot of thymine, which can bind strongly with our aptamer with a complementary strand to it. The use of 'Poly T' is used in several articles.[1][2][3] Its 3' end is conjugated to biotin[4] to bind with streptavidin.

ssDNA, capture probe of control line for RPA method

The capture strand composes the control line of our test strip, which is complementary to the reporter probe on Au nanoparticle. This allows the capture of Au particle at any time with a toxin or not, to verify the function of lateral flow assay.

Characterisation of this part

Design

Besides aptamers, we have some short single stranded DNA known as 'probes', which binds to the reporter probe on Au nanoparticle. BBa_K3593006 is one of those so-called 'probes' in our design, in which it reports a red color anyway on the control line, to verify the function of lateral flow construction.[1]
