What are DTG syringe columns used for?
DTG syringe columns are used for purifying proteins and antibodies—specifically His-tagged proteins (IMAC) and IgG antibodies (ProA)—without the need for centrifuges, pumps, or magnetic setups

Do I need any special equipment to use them?
No special equipment is required. Just connect the syringe to your sample and buffers—everything is controlled manually using a standard 5 mL syringe.

How much protein or antibody can I purify?

• IMAC columns can purify up to 7 mg of His-GFP.

• ProA columns recover 74–76% IgG from serum or culture supernatants.

Can the columns be reused?
Yes! Both IMAC and ProA syringe columns can be reused up to 10 times with consistent performance when properly handled and stored.

What makes syringe columns better than spin columns or magnetic beads?
DTG syringe columns combine high yield, manual control, and reusability, while eliminating the need for expensive equipment or single-use formats—making them faster and more cost-effective.

What volume do the columns handle?
Each column contains 100 µL of resin, ideal for processing up to 1 mL of sample.

How do I store the columns after use?
Just cap the syringe and store it at 4 °C in buffer. The resin remains hydrated—no drying or repacking required.

Can I try them before buying?
Yes! We offer free demo packs that include one IMAC and one ProA syringe column. You just cover shipping.
