Is the NB500-169 still available in the concentration of 2mg/ml? We ordered five vials in the past month with the unit size 0.1 mg. Three of them arrived with a concentration of 2mg/ml, the last two vial with a concentration of 1mg/ml. Can we influence the concentration when ordering?

In terms of the concentration of the vials, unfortunately sometimes the concentrations of our products may change. (The concentration of each vial is that stated on the label.) I am sorry, but it is not possible for you to order specifically 2 mg/ml vials of NB500-169. (If you require a concentration of 2 mg/ml, you may be interested in our Antibody Concentration and Clean Up Kit (product code for 1 spin column is 861-0005; 3 spin columns is 861-0010), which you could use to reduce the volume of the antibody by half and hence double the concentration.)

Antibody Purification Kit

Product Summary

Antibodies are sometimes only available at low concentrations and often contain low molecular weight substances that interfere in labeling reactions with enzymes, biotin, streptavidin and fluorophores.

Features	Benefits
Quickly and easily concentrate antibodies and proteins	Easy and quick to use
Remove non-protein additives such as sodium azide, tris and glycine	High recoveries, around 60 - 100%
Perform a simple buffer exchange for more favourable conjugation conditions	Suitable for Lightning-Link kits and for other kits

The antibody concentration and clean-up kit method utilizes a simple spin column to easily and quickly remove excess buffer from the antibody thereby providing a more concentrated antibody solution.

Background: AbSelect (TM) Antibody Concentration and Clean Up

The Antibody concentration and Clean Up Kit allows for the quick and easy concentration of antibodies and proteins. Antibodies are sometimes only available at low concentrations and often contain low molecular weight substances that interfere in labeling reactions with enzymes, biotin, streptavidin and fluorophores. The kit can also be used to reduce the concentration of many unwanted additives often found in antibody formulations such as azide, glycine or tris. The antibody clean up kit method utilizes a simple spin column to easily and quickly remove excess buffer from the antibody thereby providing a more concentrated antibody solution. The clean up kit also allows the experimenter to perform a simple buffer exchange to transfer the antibody into a more favorable conjugation buffer.
