Introduction

The Thermo Scientific NeutrAvidin Protein is a chemically modified version of avidin with a molecular weight of

approximately 60,000. Unlike avidin, NeutrAvidin Protein has no carbohydrate portion and a neutral isoelectric point (pI =

6.3), resulting in minimal nonspecific binding.

1

NeutrAvidin Protein immobilized onto 6% crosslinked beaded agarose is leak

resistant, stable at pH 2-11 and suitable for gravity flow, spin and FPLC methods. This resin can be used to separate

biotinylated products from non-biotinylated products and to affinity purify antigens when used with biotinylated antibodies.

Important Product Information

• To elute biotinylated molecules from the NeutrAvidin Agarose Resins, use 8M guanidine•HCl, pH 1.5 (Product No.

24115) or boil the beads in SDS-PAGE sample buffer. For non-denaturing elution conditions, biotinylate the protein

using NHS-Iminobiotin (Product No. 21117), which binds to NeutrAvidin Protein at pH 9.5 and dissociates at pH 4.

Alternatively, use a thiol-cleavable biotinylation reagent such as NHS-SS-Biotin (Product No. 21331).

Guanidine•HCl may irreversibly damage the protein of interest. Furthermore, this harsh elution condition may result in

leaching of NeutrAvidin Protein subunits and a considerable reduction in resin binding capacity from the loss of these

subunits. Monomeric Avidin (Product No. 20228) allows for gentle elution conditions to recover biotinylated molecules

without protein subunit contamination or reducing the column’s binding capacity.

The protocols included in these instructions are examples of applications for this product. Using specific applications and

systems requires optimization.

When using 1mL of resin in a 5mL or larger column, incubate the resin with the biotinylated molecule for at least

10 minutes. Omitting incubation may result in decreased binding capacity.

Gravity-flow Column Method for Purifying Antigens

A. Materials Required

• Biotinylated antibody: Use approximately 3mg of biotinylated antibody/mL of the settled NeutrAvidin Agarose Resin or

8mg of biotinylated antibody/mL of settled High Capacity NeutrAvidin Agarose Resin (2mL of the 50% slurry is

equivalent to 1mL of settled resin). Prepare biotinylated antibody at 0.2-10mg/mL in Binding Buffer.

Sample containing antigen of interest

Binding Buffer: Phosphate-buffered saline (e.g., 0.1M phosphate, 0.15M sodium chloride; pH 7.2; Product No. 28372)

Elution Buffer: Thermo Scientific Pierce IgG Elution Buffer (Product No. 21004), Gentle Ag/Ab Elution Buffer (Product

No. 21027) or 0.1M glycine•HCl, pH 2.8

Empty columns: Disposable Polystyrene Columns (Product No. 29920 for ≤ 2mL of resin or Product No. 29924 for

2-10mL of resin)

B. Procedure

1. Pack NeutrAvidin Agarose Resin into the column.

Note: When using packed columns, remove the top cap first, empty the storage solution and then remove the bottom cap.

This procedure prevents air bubbles from being drawn into the resin.

2. Equilibrate column with 3-5 column volumes of Binding Buffer.

3. Add biotinylated antibody solution to the column and allow solution to enter the resin bed. Replace the bottom and top

caps sequentially and incubate at room temperature for 10 minutes.

Note: If the solution volume is such that the entire sample cannot be added at once, incubate for 10-15 minutes and allow

some of the solution to pass through the column. Then add more antibody solution and incubate. Do not exceed the

resin’s binding capacity.

4. Wash column with 5-10 column volumes of Binding Buffer.

5. Add antigen sample in the column and allow the solution to enter the resin bed. Replace the bottom and top caps

sequentially and incubate at room temperature for 30 minutes or overnight at 4°C.

6. Wash the column with 5-10 column volumes of Binding Buffer.

Note: If using Gentle Ag/Ab Elution Buffer, wash column with three column volumes of Tris-buffered saline before

antigen elution. The Gentle Elution Buffer is not compatible with phosphate-based buffers.

7. Elute the antigen with 5-10 column volumes of Elution Buffer. Collect the eluate in 0.5-1mL fractions. If using IgG

Elution Buffer or 0.1M glycine•HCl, pH 2.8, immediately adjust the pH by the adding 100µL of 1M Tris, pH 7.5-9.0 per

1mL of sample. Monitor protein content by measuring the absorbance of each fraction at 280nm.

8. Desalt or dialyze the eluted fractions into a buffer suitable for the downstream application.

Note: Wash the immobilized biotinylated-antibody column with 10 column volumes of Binding Buffer before using it to

purify more antigen. To store column, add a final concentration of 0.02% sodium azide and store at 4°C.

Gravity-flow Column Method for Purifying Biotinylated Molecules

Batch Method for Immunoprecipitation

A. Materials Required

Sample containing antigen of interest

Biotinylated antibody: Use approximately 3mg of biotinylated antibody/ml of settled NeutrAvidin Agarose Resin or 8mg

of biotinylated antibody/mL of settled High Capacity NeutrAvidin Agarose Resin (2mL of the 50% slurry is equivalent

to 1mL of settled resin). Prepare biotinylated antibody at 0.2-10mg/mL in Binding Buffer.

Binding Buffer: Phosphate-buffered saline (e.g., 0.1M phosphate, 0.15M sodium chloride; pH 7.2; Product No. 28372).

To reduce nonspecific binding, add 0.1% SDS, 1% NP-40 or 0.5% sodium deoxycholate to the buffer.

Elution Buffer: For eluting the antigen only, use Pierce IgG Elution Buffer (Product No. 21004), Gentle Ag/Ab Elution

Buffer (Product No. 21027) or 0.1 M glycine•HCl, pH 2.8. For eluting the biotinylated molecule, use

8 M guanidine•HCl, pH 1.5 or boil the beads in SDS-PAGE sample buffer.

Microcentrifuge tube(s)

B. Procedure

The amount of antigen needed and the incubation time are dependent upon the antibody-antigen system used and require

optimization for each specific system.

To allow for proper mixing, make sure the total reaction volume does not completely fill the microcentrifuge tube.

1. In a microcentrifuge tube, solubilize antigen in 50µL of Binding Buffer and add the biotinylated antibody. Adjust the

sample volume to 0.2mL with Binding Buffer. Incubate sample overnight at 4°C.

2. Mix the NeutrAvidin Agarose Resin to ensure an even suspension. Add the appropriate amount of resin to the tube

containing the antigen/biotinylated antibody mixture. Incubate the sample with mixing for 1 hour at room temperature or

4°C.

3. Wash the resin-bound complex with 0.5-1.0mL of Binding Buffer. Centrifuge for 1-2 minutes at ~2500 × g and remove

the supernatant. Repeat this wash procedure at least four times and remove the final wash.

Note: If using Gentle Ag/Ab Elution Buffer, wash resin with Tris-buffered saline before antigen elution. The Gentle

Elution Buffer is not compatible with phosphate-based buffers.

4. Add elution buffer to the resin to recover the bound antigen. If using Pierce IgG Elution Buffer or 0.1M glycine•HCl,

pH 2.8, remove the liquid and immediately adjust the pH by adding a concentrated buffer such as 1M Tris, pH 7.5-9.0

(add 100µL of this buffer to 1mL of sample). Alternatively, boil the resin-bound complex in SDS-PAGE sample buffer.
