IRDye 680LT Goat anti-Mouse IgG2b Secondary Antibody.

Highly cross-adsorbed goat anti-mouse IgG_2b (γ 2b chain specific) antibody conjugated to IRDye 680LT.

Immunogen

Mouse IgG_2b paraproteins

Purity and Specificity

Isolation of specific antibodies was accomplished by affinity chromatography on mouse IgG_2b covalently linked to agarose. Based on ELISA and flow cytometry, the antibody reacts with the heavy chain of mouse IgG_2b. This antibody was tested by dot blot and/or solid-phase adsorbed to ensure minimal cross-reactivity with mouse IgM, IgG₁, IgG_2a, 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.

Applications

On-Cell Western Assay

Formulation

IRDye 680LT Secondary Antibodies are supplied as purified immunoglobulin conjugates, lyophilized in phosphate-buffered saline, pH 7.4. Protect from light. Store at 4 °C prior to reconstitution.

Each vial contains 10 mg/mL BSA (free of IgG and protease) as a stabilizer and 0.01% sodium azide as a preservative, after reconstitution. Concentration is 1.0 mg/mL when reconstituted as directed. Refer to the pack insert for details on reconstitution.

Recommended Dilutions

Application	Recommended	Suggested Range
Odyssey Western blot detection	1:20,000	1:10,000 - 1:50,000
Other	User optimized

Optimum dilutions will vary and should be determined empirically.

Note: When using PVDF membranes for Western blotting applications, SDS (final concentration of 0.01 - 0.02%) and Tween^® 20 (final concentration of 0.1 - 0.2%) must be added during the detection incubation step to avoid non-specific background staining.

Example Data

IRDye 680LT Goat anti-Mouse IgG2b-Specific Secondary Antibody data — **Western blot detection of p53 in various lysates.** Lanes 1-5: Odyssey^® One-Color Molecular Weight Marker (P/N 928-40000), Hela, COS7, A431, and C32 cell lysates. The membrane was blocked with Odyssey Blocking Buffer (P/N 927-40000) and probed with mouse anti-p53 (IgG_2a) (Santa Cruz P/N sc-126) and Mouse anti-β Actin (IgG_2b) (P/N 926-42212) followed by detection with IRDye 800CW Goat anti-Mouse IgG_2a (P/N 926-32351) and IRDye 680LT Goat anti-Mouse IgG_2b (P/N 926-68052).
