MIP 4 Human

What is Human CCL4/MIP-1 Beta and what is its role in human biology?

CCL4/MIP-1 beta is a chemokine belonging to the CC chemokine family that plays crucial roles in inflammatory responses by attracting various immune cells including monocytes, dendritic cells, and natural killer cells to sites of inflammation. It is primarily produced by macrophages, dendritic cells, and lymphocytes in response to inflammatory stimuli. In research contexts, CCL4/MIP-1 beta is studied for its involvement in various inflammatory conditions, HIV infection (as it can block HIV entry into cells), and cancer immunology.

How does CCL4/MIP-1 Beta differ from other chemokines in the same family?

CCL4/MIP-1 beta shares structural similarities with other CC chemokines but has distinct receptor specificity, primarily binding to CCR5. Unlike some other chemokines that interact with multiple receptors, CCL4/MIP-1 beta has a relatively specific interaction profile. It differs from its close relative CCL3 (MIP-1 alpha) in amino acid sequence and certain functional aspects despite their similar roles in inflammation. CCL4 exists in different isoforms, with the Act-2 variant being commonly used in recombinant protein production for research purposes .

What are the normal concentration ranges of CCL4/MIP-1 Beta in human biological samples?

The normal concentration ranges of CCL4/MIP-1 beta vary depending on the biological sample type and individual health status. In standard research settings using validated ELISA methods, typical ranges can be detected from pg/mL to ng/mL levels. Based on the ELISA kit data, validated samples were tested at concentrations ranging from approximately 23-932 pg/mL, with different samples showing different concentration ranges . It's important to note that these values can vary significantly based on health status, with elevated levels often observed in inflammatory conditions.

What are the most reliable methods for measuring human CCL4/MIP-1 Beta in different biological samples?

The most reliable method for measuring human CCL4/MIP-1 beta is enzyme-linked immunosorbent assay (ELISA), specifically sandwich ELISA techniques. The Quantikine Human MIP-1 beta Immunoassay is a validated solid-phase ELISA designed to measure MIP-1 beta in multiple sample types. This assay takes 3.0 to 4.5 hours to complete and has been shown to accurately quantitate both recombinant and natural human MIP-1 beta . Other methods include multiplex bead-based assays (for simultaneous measurement of multiple cytokines), quantitative PCR (for measuring mRNA expression), Western blotting (for semi-quantitative protein detection), and flow cytometry (for intracellular detection in specific cell populations).

How should I design sampling protocols for optimal CCL4/MIP-1 Beta detection?

For optimal CCL4/MIP-1 beta detection, consider these methodological guidelines:

• Sample collection timing: Since chemokine expression can fluctuate, standardize collection times.

• Sample processing: Process samples immediately or store at -80°C with minimal freeze-thaw cycles to preserve protein integrity.

• Anticoagulant selection: Based on the ELISA kit validation data, samples can be collected in EDTA, heparin, or citrate tubes for plasma, with each showing comparable recovery rates (EDTA: 84-112%, Heparin: 90-112%, Citrate: 87-116%) .

• Pre-analytical variables: Control for factors like fasting status, medication use, and recent infections that might influence CCL4 levels.

• Cell culture conditions: For in vitro studies, standardize cell density, passage number, and stimulation conditions. The kit shows proper recovery in cell culture media (81-117%) .

• Appropriate controls: Include both positive controls (samples with known CCL4 concentrations) and negative controls.

• Spike-recovery testing: Consider spiking samples with known amounts of recombinant CCL4 to validate detection in your specific sample matrix.

What are the critical parameters to consider when using ELISA for human CCL4/MIP-1 Beta quantification?

When using ELISA for human CCL4/MIP-1 beta quantification, consider these critical parameters:

• Assay sensitivity: Ensure your expected concentration range falls within the assay's dynamic range.

• Specificity: Verify the antibodies used have minimal cross-reactivity with other chemokines, especially CCL3/MIP-1 alpha.

• Sample dilution: Proper sample dilution is essential to ensure measurements fall within the standard curve.

• Precision: The inter-assay and intra-assay coefficient of variation (CV%) should ideally be <10%. The data shows that for cell culture supernates, intra-assay precision was 3.8-4.7% CV and inter-assay precision was 5.9-11.8% CV. For serum/plasma samples, intra-assay precision was 3.2-9.0% CV and inter-assay precision was 7.1-9.7% CV .

• Recovery: Ensure acceptable recovery rates in your specific sample matrix. The kit shows recovery rates of 99-107% across different sample types .

• Linearity: Check if samples can be diluted while maintaining proportional concentration readings.

• Standard curve quality: R² value should be >0.99 for reliable quantification.

• Temperature and timing: Maintain consistent incubation temperatures and times according to protocol.

  • Avoid linear regression for full-range ELISA curves as chemokine ELISAs typically have sigmoidal response curves

How does sample matrix affect CCL4/MIP-1 Beta measurements and how can I account for matrix effects?

Sample matrix significantly impacts CCL4/MIP-1 beta measurements through several mechanisms:

• Matrix interference sources:

  • Binding proteins that sequester CCL4 or block antibody access

  • Endogenous antibodies that may cross-react with assay components

  • Lipids, particularly in lipemic samples, that can non-specifically bind proteins

  • Hemolysis, which introduces intracellular components that may interfere with detection

  • Varying protein concentrations across sample types that affect molecular interactions

• Matrix-specific considerations:

  • Serum vs. plasma: The coagulation process in serum preparation can release additional chemokines from platelets

  • Cell culture media: Components like fetal bovine serum may contain bovine chemokines or other interfering factors

  • Tissue homogenates: Contain diverse cellular contents that may affect antibody binding

• Quantitative impact according to kit data :

  • Cell culture media: 81-117% (average 107%)

  • Serum: 88-113% (average 99%)

  • EDTA plasma: 84-112% (average 100%)

  • Heparin plasma: 90-112% (average 99%)

  • Citrate plasma: 87-116% (average 99%)

• Strategies to account for matrix effects:

  • Spike-recovery testing: Add known amounts of recombinant CCL4 to each matrix type

  • Parallel line analysis: Compare dilution linearity between standards and samples

  • Sample-specific standard curves: Prepare standards in the same matrix as samples when possible

  • Optimized sample dilution: Dilute samples sufficiently to minimize matrix effects while maintaining signal
