Anti-CD11b antibody [M1/70] {ER780} (STJA0003899)

What it means: Monoclonal antibodies originate from a single hybridoma clone that recognizes one defined epitope on the target antigen — making Monoclonal antibodies uniquely consistent between lots.

Why it matters:

• Monoclonal antibodies offer lot-to-lot reproducibility that is critical for longitudinal studies, quantitative assays, and any experimental design requiring matched performance across timepoints or collaborating labs.
• The defined single-epitope binding profile enables reliable pairing with a non-competing capture antibody for sandwich ELISA, proximity ligation, and flow cytometry multiplex panels.

How to interpret here: A single, well-optimized titration for this Monoclonal antibody transfers reliably across experiments. Confirm whether the target epitope is preserved under your fixation or denaturation conditions before proceeding with IHC or WB applications.

What it means: This antibody was raised in Rat, producing Rat-derived IgG antibodies with species-specific secondary antibody compatibility.

Why it matters:

• The Rat host species determines which secondary antibody you need for indirect detection — select an anti-Rat IgG secondary matched to your detection label (HRP, fluorochrome, or biotin).
• Use secondaries specifically validated for Rat IgG. Verify cross-adsorption status if your sample matrix contains endogenous Rat immunoglobulins.

How to interpret here: Confirm availability of an anti-Rat secondary antibody in your lab before ordering. For multiplex IF, pair this Rat-raised antibody with antibodies from a different host species to avoid secondary antibody cross-reactivity.

What it means: Validated reactivity to Human/Mouse — this antibody cross-reacts with orthologs from multiple species within a single reagent.

Why it matters:

• Cross-species reactivity (Human/Mouse) allows direct comparison of the same target across Human and Mouse experimental models without switching antibodies, eliminating an important source of inter-study variability.
• All listed reactivities are experimentally confirmed, not computationally predicted — critical for reviewers and reproducibility standards.

How to interpret here: Confirm that your specific species is among the validated list (Human/Mouse). Reactivity to unlisted species should be independently validated before use in publication-quality data.

What it means: ER780 format indicates this antibody carries a specific label enabling direct detection in compatible assay systems.

Why it matters:

• The ER780 conjugate eliminates the secondary antibody incubation step, shortening your protocol and reducing non-specific background from secondary reagents.
• Directly labeled antibodies like this ER780 format are particularly advantageous in multiplex panels where multiple primary antibodies from the same host species must be distinguished simultaneously.

How to interpret here: Confirm instrument or substrate compatibility with the ER780 label. Store per datasheet to preserve label integrity — light-sensitive conjugates require protection from light.

What it means: IgG2bk is the immunoglobulin class and subclass of this antibody, defining its constant-region structure and effector functions.

Why it matters:

• Isotype IgG2bk determines which secondary antibody constant-region specificities are compatible — isotype-specific anti-IgG1 or anti-IgG2a secondaries enable discrimination of co-stained antibodies from the same host species in multiplex experiments.
• For functional assays, isotype identity guides selection of Fc-receptor binding controls and isotype-matched negative controls required for rigorous experimental design.

How to interpret here: Use a negative control of the same isotype (IgG2bk) to assess non-specific binding in your assay. If performing multiplex staining with multiple antibodies from the same species, select isotype-specific secondary antibodies to resolve each IgG2bk signal independently.

What it means: M1/70 is the unique clone designation of this monoclonal antibody, identifying the specific hybridoma lineage that defines its epitope and performance characteristics.

Why it matters:

• Clone M1/70 allows precise cross-referencing with published literature — if peer-reviewed studies cite this specific clone, its performance in your assay context is already independently validated.
• Recording clone M1/70 in your methods section enables collaborators and reviewers to replicate your exact reagent, satisfying increasingly stringent journal antibody reporting requirements (RRID registration, clone number disclosure).

How to interpret here: Search clone M1/70 in published literature and antibody validation databases to review independent performance data. Always record the full clone designation in experimental notes for complete reproducibility documentation.

What it means: This antibody has been experimentally validated for 1 application: Flow Cytometry.

Why it matters:

• Flow Cytometry
• Each listed application represents an independently optimized protocol — not a theoretical prediction — giving you confidence that the antibody will perform reliably when used at the recommended conditions for that technique.

How to interpret here: Select the application that matches your assay (Flow Cytometry) and refer to the datasheet for the validated dilution range specific to each technique. Using this antibody outside the listed validated applications requires independent optimization and performance verification.
