BioPAL provides the research community with a chelated conjugates of albumin designed for PET imaging and radiotherapy research applications.  There are approximately 10 to 15 chelates conjugated to albumin.  The molecular weight of the albumin conjugate is ~74 kDa.  The conjugate is supplied as a 1 ml solution containing 10 mg of protein in a 2 ml serum vial.  In order to use these materials, the researcher must add his/her radiolabel to about 1 mg of appropriate albumin chelate, incubate for a short time, and purify the product by passing over a G-25 column.  Chelated conjugates of albumin are also provided co-labeled with fluorescent dyes.

BioPAL has developed PROTrack^TM technology to enable researchers to locate, track, and quantify proteins of interest in in vivo system.  PROTrack is a line of protein labeling kits and is designed for applications in nuclear medicine involving studies related to PET imaging and radiotherapy.  The kits are available with different chelates designed specifically for isotopes such as yttrium-90, bismuth-213, gallium-68, and ziconium-89.
