IRDye 680LT Goat anti-Mouse IgG1-Specific Secondary Antibody.

IRDye® 680LT Goat anti-Mouse IgG1-Specific Secondary Antibody

IRDye 680LT Goat anti-Mouse IgG1-Specific Secondary Antibody.


Mouse IgG1 paraproteins

Purity and Specificity

Isolation of specific antibodies was accomplished by affinity chromatography on mouse IgG1 covalently linked to agarose. Based on ELISA and flow cytometry, the antibody reacts with the heavy chain of mouse IgG1. This antibody has been tested by dot blot and/or solid-phase adsorbed to ensure minimal cross-reactivity with mouse IgM, IgG2a, IgG2b, IgG3, and IgA, pooled human sera, and purified human paraproteins. The conjugate has been specifically tested and qualified for Western blot applications. Results with your primary antibody may vary and specificity should be confirmed prior to performing two-color detection.

Example Data

IRDye® 680LT Goat anti-Mouse IgG1 Specific Secondary Antibody data
Western blot analysis of PTEN expression in mouse PTEN transfected 293T whole cell lysate (lane 2) and non-transfected 293T lysate (lane 3). Both lysates were loaded with 2 µg total protein per lane. Odyssey® One-Color Molecular Weight Marker (P/N 928-40000) was loaded in lane 1. The blot was probed with mouse ant-PTEN (IgG2b) (Santa Cruz P/N sc-133197) and mouse anti-GAPDH (IgG1) (Abcam P/N ab8245) followed by detection with IRDye 800CW Goat anti-Mouse IgG2b (P/N 926-32352) and IRDye 680LT Goat anti-Mouse IgG1 (926-68050)

Selected P/N: 926-68050
