The fastest tools for quantitative testing of your primary antibody’s specificity, binding, and internalization, providing results in 1 day.
Fab-pHast products bind to your primary antibody via a secondary antibody cross-linked to a pH-dependent fluorescent reporter. This fluorescent reporter increases intensity as the pH of its surroundings becomes more acidic, as evident when exposed to the environment inside a cell.

PH-01 Fab-pHast human
SLC46A3 as a Potential Predictive Biomarker for Antibody-Drug Conjugates Bearing Noncleavable Linked Maytansinoid and Pyrrolobenzodiazepine Warheads. Kinneer K, et al. Clin Cancer Res, 24 (24):6570-6582, 2018.

Objective: To develop biomarkers to uncover the underlying mechanism of resistance by certain cell lines for ADCs.
Summary: Loss of SLC46A3 expression was found to be a mechanism of innate and acquired resistance to ADCs bearing DM1 and SG3376.
Dose: For Lysosomal trafficking, ADCs were labeled with Fab-pHast human. Cells were incubated with 3 mg/mL of labeled ADCs at 37°C for desired time points and fluorescence quantified by flow cytometry.

Parental HEK-293 cells, and HEK-293 cells transfected with the p75 receptor, were plated in a 96-well plate overnight. Titrated 192-IgG antibody (Cat. #AB-N43) was incubated at RT with 50 nM of Fab-pHast Mouse (Cat. #PH-02) for 20 min prior to addition to cells. Plates were incubated overnight to allow maximum internalization, but a few hours is sufficient for detection.
