Frequently asked questions

GemChem Binders

Do I need to biotinylate my antibody?

Yes, for streptavidin binders.

Can I use my own antibody?

Yes. The evaluation uses your own antibody.

Does this allow test development on both NC and unmodified cellulose test strips?

It is designed to allow it in some formats. See the Validation page for status.

Can you make a binder for another material?

Yes, for most materials used in life science applications. See Custom binders on the GemChem page.

Is it research use only?

Currently, yes.

Can I use my own antibody?

Yes. The evaluation uses your own antibody.

Do I need to biotinylate my antibody?

For the streptavidin conjugate, yes. The Protein G conjugate binds unmodified antibodies.

What is the difference between the citrate nanospheres and the conjugates?

The nanospheres are citrate-capped gold for your own conjugation. The conjugates arrive with the capture protein already oriented on the gold.

Can I get a different particle size?

Yes, within the range of 10nm to 40nm, at current time.

Is it research use only?

Currently, yes.
