This product is manufactured using SureLight® allophycocyanin which is a product of Columbia Biosciences.

APC is an ultra-sensitive phycobiliprotein that exhibits far-red fluorescence (absorbs at 653nm and emits at 660nm). The intense brightness of APC means it is popular for flow cytometry/FACS and T-cell labeling.

This product is manufactured using SureLight® Allophycocyanin which is a product of Columbia Biosciences, and uses a proprietary non-destructive cross-linking process that increases the thermal stability while maintaining fluorescent and spectral integrity of the native dye.

Generate antibody-APC conjugates in only 30-seconds hands on time, 2 hours total.

The antibody labeling procedure simply requires mixing oYo-Link® SureLight® APC with the desired antibody followed by photocrosslinking with non-damaging black light (365 nm) for 2 hours. 

Photocrosslinking can be carried out in most buffers, including those containing amine-containing molecules (e.g. TRIS, glycine) or storage proteins (see Buffer Compatibility Table).

Excitation/Emission: 653nm/660nm

Applications: Flow Cytometry/FACS, T-cell labeling.

Requirements: To label your compatible antibodies with oYo-Link®, you will need a light source emitting at 365nm (6-10W). Purchase AlphaThera’s LED Photo-Crosslinking Device here, or use a compatible device.

Will oYo-Link work with my antibody?

Please check the antibody compatibility table. Note: oYo-Link mIgG1 can be used to label mouse IgG1 antibody. Currently, oYo-Link mIgG1 is only available for certain products. Please check the product webpage. oYo-Link mIgG1 only labels mouse IgG1 and is not compatible with other antibodies.

Can oYo-Link be used to label antibodies in the presence of albumin and/or Tris?

Yes, since oYo-Link specifically bind to the heavy chain of IgG, it works in the presence of both albumin and Tris. oYo-Link is compatible with all common buffers. See the full buffer compatibility table here.

If an oYo-Link product has accidentally been left at room temperature for a week, will it still work?

With the exception of oYo-Link DBCO, all oYo-Link products are shipped as white or clear pellets and are very stable. While we recommend cold storage, they will not exhibit any loss of activity if left at room temperature for a week. oYo-Link DBCO must be shipped and stored cold (-20°C) immediately upon arrival, otherwise there will be a loss in activity.

Does AlphaThera offer conjugation service?

Yes. You can find more information about our conjugation services here.

How many oYo-Link labels will be conjugated to each antibody?

For most subclasses and species of antibody, oYo-Link will result in the conjugation of 2 labels per antibody (maximum), one label per heavy chain. For example, ~95% of human IgG and Rabbit IgG will have two labels per antibody. However, there are a few antibodies such as mouse IgG2b and goat IgG, where the conjugation is slightly less efficient. In this case, 60 to 80% of the antibody will be labeled and have a mixture of 0, 1 and 2 labels per antibody. See the antibody conjugation efficiency here

How do I know if oYo-Link was successfully conjugated to my antibody?

Antibody conjugation can be checked on SDS-PAGE gel. An example is present in the supporting data on each product page.

Does 365nm UV illumination damage the antibody and its binding affinity?

The conjugated and unconjugated antibody binding affinities have been tested via both ELISA and cell binding assays and don’t show any difference.

Do I need to remove free oYo-Link after conjugating to antibody?

For most immunoassay applications, purification is not necessary. In our standard recommended protocol, the molar ratio of oYo-Link-to-antibody is 5:1. These conditions ensure that the antibody conjugation efficiency reaches its maximum; however there will be a slight excess remaining in your antibody mixture. This is usually removed during immunoassay washing steps. However, if your application requires high antibody-conjugate purity, please contact us for more information on this process and for a detailed protocol.

What is the lowest amount of antibody that can be labeled by oYo-Link reagents?

We recommend working with at least 1 µg of antibody; however, it is possible that even lower amounts of antibody can be labeled.

Can antibodies that are highly dilute be labeled by oYo-Link reagents?

Yes, antibodies can be efficiently labeled even if diluted to concentrations as low as 50 µg/mL.
