产品概述
Streptavidin Conjugation Kit / Streptavidin Labeling Kit ab102921 uses a simple and quick process for streptavidin labeling / conjugation of antibodies. It can also be used to conjugate other proteins or peptides. Learn about our antibody labeling kits and their advantages.
To conjugate an antibody to Streptavidin using this kit:
- add modifier to antibody and incubate for 3 hrs
- add quencher and incubate for 30 mins
The conjugated antibody can be used immediately in WB, ELISA, IHC etc. No further purification is required and 100% of the antibody is recovered for use.
Learn about buffer compatibility below; for incompatible buffers and low antibody concentrations, use our rapid antibody purification and concentration kits. Use the FAQ to learn more about the technology, or about conjugating other proteins and peptides to Streptavidin.
Custom size conjugation kits up to 100 mg are available on demand. Please contact us to discuss your requirements.

说明
This product is manufactured by Expedeon, an Abcam company, and was previously called Lightning-Link® Streptavidin Labeling Kit. 708-0005 is the same as the 100 µg size. 708-0010 is the same as the 3 x 100 ug size. 708-0030 is the same as the 3 x 10 ug size. 708-0015 is the same as the 1 mg size.

Antibodies > 5mg/ml or < 0.5 mg/ml should be diluted /concentrated.
Buffer Requirements for Conjugation
Buffer should be pH 6.5-8.5.
Compatible buffer constituents
If a concentration is shown, then the constituent should be no more than the concentration shown. If several constituents are close to the limit of acceptable concentration, then this can inhibit conjugation.50mM / 0.6% Tris1 0.1% BSA 50% glycerol 0.1% sodium azide PBS Potassium phosphate Sodium chloride HEPES Sucrose Sodium citrate EDTA Trehalose 1 Tris buffered saline is almost always ≤ 50 mM / 0.6%
Incompatible buffer constituentsThiomerosal Proclin Glycine Arginine Glutathione DTT If a constituent of the buffer containing your antibody or protein is not listed above, please check the FAQ or contact us.
Only purified antibodies are suitable for use, ie. where other proteins, peptides, or amino acids are not present: antibodies in ascites fluid, serum or hybridoma culture are not suitable for conjugation.
Storing and handling conjugation kits
Lyophilized Lightning-Link® components are hygroscopic.
Kits are intentionally shipped at ambient temperature with silica gel to avoid exposure to moisture. Upon receipt, store the kit frozen and protect from moisture. Before opening the outer container, allow the lyophilized components to reach room temperature to minimize condensation.
