Company:

LI-COR Biosciences

Product Name:

IRDye 680RD Secondary Antobody Goat Anti-Rabbit

Catalog Number:

926-68071

Following overnight incubation with primary rabbit antibodies, we selected this secondary anti-rabbit antibody to be able to detect specific proteins in a number of samples.

Experimental Design and Results Summary

Applications

Western Blot

Sample

Total eIF2a

Primary Incubation

Primary antibody suggested dilution overnight at 4 degrees C.

Blocking Agent

Li-Cor Odyssey Block for 1 hour.

Secondary Incubation

1:15,000 Li-Cor IRDye 680RD, 0.1% tween, 0.02% SDS, in 1:3 odyssey block: TBS at room temperature for 1 hour

Tertiary Incubation

NA

Detection

Li-Cor Odyssey infrared Imaging system

Results Summary

We have had continued success with Li-Cor secondary antibody products. Proteins are clearly visible using the Odyssey Infrared Imaging system. The bonus is the dilution factor is 1:15,000, allowing this product to last for a long time. DO NOT leave membrane or antibody exposed to light for long as signal will become weak.

Additional Notes

We have had success multiplexing this with the IRDye800CW green secondary antibody
