SLAM Family Member 8 ELISA (SLAMF8 / BLAME / CD353) – Quantitative Sandwich ELISA for Myeloid Cell Research

SLAMF8 as a myeloid and lymphoid receptor

SLAM family member 8 (SLAMF8, also called BLAME or CD353) is a type I transmembrane receptor belonging to the CD2/SLAM subfamily of the immunoglobulin superfamily. It is encoded by the SLAMF8 gene, which is part of the CD2/SLAM cluster on chromosome 1 and is mainly detected in myeloid cells and specific lymphocyte populations. PubMed+1

Authoritative gene and protein resources include NCBI Gene entries for SLAMF8 in human and mouse, hosted by the U.S. National Library of Medicine at the National Institutes of Health (NIH):

For background on what genes are and how they are organized in the genome, many researchers refer to Genome.gov – Genes fact sheet, produced by the U.S. National Human Genome Research Institute.

SLAMF8 is strongly associated with:

  • Macrophages and monocytes, particularly under activation by interferon-γ or bacterial signals PMC+1

  • Dendritic cells, where SLAM receptors participate in pattern recognition and antigen-presentation pathways

  • Selected T-cell subsets, especially those infiltrating certain experimental models Nature

Functional role of SLAMF8 in macrophage and dendritic-cell signaling

SLAMF8 has become a key marker for researchers studying myeloid cell activation, NADPH oxidase regulation, and pattern-recognition receptor signaling. Multiple studies show that Slamf8 acts as a negative regulator of Nox2-dependent reactive oxygen species (ROS) in macrophages exposed to various stimuli. PMC+2Frontiers+2

Important open-access references hosted on NIH platforms include:

These articles describe how Slamf8-deficient macrophages show increased Nox2 activity and altered ROS generation in response to experimental stimuli. In parallel, work published in Frontiers in Immunology and indexed at PubMed Central demonstrates that SLAMF8 down-regulates microbicidal activity and ROS-linked mechanisms in model systems.

Principle of the SLAMF8 ELISA assay

Most SLAM family member 8 ELISA kits use a solid-phase sandwich ELISA format, a widely accepted method described in detail in several NCBI and PubMed resources:

In a typical SLAMF8 sandwich ELISA, the workflow is:

  1. Capture phase
    A monoclonal or polyclonal antibody specific for SLAMF8 is coated onto the wells of a 96-well microplate. After blocking, the surface is ready to bind SLAMF8 from samples or standards.

  2. Sample incubation
    Standards with known SLAMF8 concentrations and unknown samples are added. During incubation, SLAMF8 in the liquid phase binds specifically to the immobilized capture antibody.

  3. Detection antibody
    A second, biotin-labeled antibody recognizing a non-overlapping epitope on SLAMF8 is added. This forms a capture–antigen–detection sandwich complex.

  4. Enzyme conjugate
    Streptavidin conjugated to horseradish peroxidase (HRP) binds to the biotin on the detection antibody, providing the enzyme activity needed for signal generation.

  5. Substrate addition and readout
    A chromogenic substrate such as TMB is added. HRP converts TMB into a colored product, and absorbance is measured in a microplate reader. The signal intensity is proportional to SLAMF8 concentration in the sample. Bio-Techne+3www.rndsystems.com+3Antibodies Online+3

Typical contents and performance characteristics of SLAMF8 ELISA kits

Although exact formulations differ between manufacturers, most SLAMF8 ELISA kits include:

  • 96-well strip microplate pre-coated with anti-SLAMF8 capture antibody

  • Recombinant SLAMF8 standard (lyophilized) for standard curve generation fn-test.com

  • Biotinylated anti-SLAMF8 detection antibody

  • HRP-streptavidin conjugate

  • Sample diluent and assay buffer

  • Wash buffer concentrate

  • Substrate solution (TMB)

  • Stop solution (often acid)

  • Detailed protocol with incubation times and recommended plate reader settings Bio-Techne+4www.rndsystems.com+4Antibodies Online+4

Key performance metrics that are attractive for SEO and highly relevant for researchers:

  • Assay type: Quantitative sandwich ELISA

  • Format: 96-well strip plate

  • Range: Typically from low picogram per milliliter to nanogram per milliliter levels

  • Sensitivity: Lower limit of detection indicated in pg/mL

  • Precision: Intra- and inter-assay coefficient of variation (CV %)

  • Specificity: Binding to SLAMF8 with minimal cross-reactivity

The way these parameters are defined is consistent with general ELISA performance descriptions in reviews hosted at PubMed and PMC. PubMed+1

Sample types and matrix considerations

A SLAM family member 8 ELISA is usually validated for one or more of the following matrices:

  • Serum and plasma from experimental animals or model systems

  • Cell culture supernatant from macrophages, dendritic cells or engineered cell lines

  • Tissue or cell lysates, where solubilized receptor can be measured after extraction

Good practice in sample handling, which follows general immunology laboratory recommendations, includes:

  • Avoiding repeated freeze–thaw cycles

  • Maintaining consistent sample dilution factors

  • Using matched anticoagulants if different plasma samples are compared

  • Including internal control samples on each plate

Detailed guidance on handling biological samples and running ELISA experiments can be found in university lab manuals such as the Immunology Lab Manual, University of Rochester and overview documents like the Immune System overview PDF from Texas A&M Veterinary Medicine. Centre Médical Rochester+1

Data analysis and interpretation in research workflows

For SLAMF8 ELISA data, researchers typically:

  1. Fit a four-parameter logistic (4-PL) or five-parameter logistic (5-PL) curve to the standard data.

  2. Calculate SLAMF8 concentrations in unknown samples from the standard curve.

  3. Normalize values to cell counts, total protein, or other reference metrics when comparing different experimental groups.

  4. Integrate SLAMF8 values with additional readouts such as cytokines quantified by multiplex ELISA panels. C et Centre National d’Information

Because SLAMF8 acts as a receptor involved in ROS modulation and cell migration, its levels are often discussed together with:

  • Markers of macrophage polarization

  • Surface receptors involved in antigen recognition

  • Signaling intermediates in NADPH oxidase complexes PMC+2Frontiers+2
