Anti-6-His Mouse Monoclonal, Cat. #AB-20 [see also Cat. #AB-213] The use of polyhistidine tags has become a popular method for protein purification, commonly used in the screening process as a tag for your protein or peptide of interest. Whether the material you are screening for is affinity purified or in crude bacterial extract, you will

HRP-labeled Saporin Goat Polyclonal, Cat. #AB-15AP-HRP HRP-labeled Anti-SAP can be used to verify binding specificity of a targeted toxin to a cell line expressing the target molecule. By first binding the targeted toxin to protein extract or plate-bound antigen, then binding HRP-labeled Anti-SAP to the targeted toxin, specificity can be confirmed through the use of

This article is a summary of data presented in reference #1. Figures 1-4 are taken from that article. This work was funded by NS045520 and DK40498 to S. Ritter. Neuropeptide Y (NPY) conjugated to saporin (SAP), a ribosomal toxin, is a compound designed to selectively target and lesion NPY receptor-expressing cells. We conducted competitive binding

Antibodies conjugated to fluorescent dyes are vibrant and vital tools at a scientist’s disposal. ATS currently has six fluorescent conjugates in our catalog: Cy3-labeled 192-IgG (Cat. #AB-N43FL3), FITC-labeled Anti-Saporin (Cat. #AB-15APFL), Alexa 488-labeled 192-IgG (Cat. #AB-N43FLA), FITC-labeled Goat anti-rabbit IgG (Cat. #FL-04), Cy3- labeled anti-NGFr (Cat. #AB-N01APFL3), and Cy5-labeled anti- NGFr (Cat. #AB-N01APFL5). ATS also

ATS continues to make progress toward human clinical trials with SP-SAP. Thanks to the financial support of the National Institutes of Health, National Institute of Mental Health, preclinical studies have been completed, protocols for drug production have been written and the first of two toxicology studies is done. This first study is a GLP toxicology

Streptavidin-ZAP (Cat. #IT-27) Saporin conjugated to streptavidin is one of the most useful reagents that we have produced at ATS. It has been used in a wide variety of studies both in academic research and pharmaceutical/biotech labs. Workers are able to easily see if their molecule, that is biotinylated, is internalized by the target cells.

Cholecystokinin (CCK) is widely distributed in the central nervous system and the gastrointestinal tract. The 33-amino acid peptide contains a carboxyl terminal octapeptide sequence Asp-Tyr-Met-Gly-Trp-Met-Asp-Phe-NH2 which confers the biological activity
