Comment:

Sequence similarities: Belongs to the intercrine beta (chemokine CC) family.

Plate: Pre-coated

Protocol: human CCL4 ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for CCL4 has been precoated onto 96-well plates. Standards(E.coli, A24-N92) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for CCL4 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human CCL4 amount of sample captured in plate.

Assay Procedure:

Aliquot 0.1 mL per well of the 500pg/mL, 250pg/mL, 125pg/mL, 62.5pg/mL, 31.3pg/mL, 15.6pg/mL, 7.8pg/mL human CCL4 standard solutions into the precoated 96-well plate. Add 0.1 mL of the sample diluent buffer into the control well (Zero well). Add 0.1 mL of each properly diluted sample of human cell culture supernates, serum or plasma(heparin, EDTA, citrate) to each empty well. See "Sample Dilution Guideline" above for details. It is recommended that each human CCL4 standard solution and each sample be measured in duplicate.

Assay Precision:

• Sample 1: n=16, Mean(pg/ml): 32, Standard deviation: 1.3, CV(%): 4.1
• Sample 2: n=16, Mean(pg/ml): 91, Standard deviation: 3.8, CV(%): 4.2
• Sample 3: n=16, Mean(pg/ml): 324, Standard deviation: 15.2, CV(%): 4.7,
• Sample 1: n=24, Mean(pg/ml): 33, Standard deviation: 2.1, CV(%): 6.4
• Sample 2: n=24, Mean(pg/ml): 87, Standard deviation: 5.8, CV(%): 6.7

Target Details for CCL4

Target: CCL4 (Chemokine (C-C Motif) Ligand 4 (CCL4))

Alternative Name: CCL4

Background:

Protein Function: Monokine with inflammatory and chemokinetic properties. Binds to CCR5. One of the major HIV-suppressive factors produced by CD8+ T-cells. Recombinant MIP-1-beta induces a dose-dependent inhibition of different strains of HIV-1, HIV-2, and simian immunodeficiency virus (SIV). The processed form MIP-1-beta(3-69) retains the abilities to induce down-modulation of surface expression of the chemokine receptor CCR5 and to inhibit the CCR5- mediated entry of HIV-1 in T-cells. MIP-1-beta(3-69) is also a ligand for CCR1 and CCR2 isoform B. .

Background: Chemokine(C-C motif) ligand 4, also known as CCL4, is a protein which in humans is encoded by the CCL4 gene. It is a CC chemokine with specificity for CCR5 receptors. It is a chemoattractant for natural killer cells, monocytes and a variety of other immune cells. CCL4 is a major HIV-suppressive factor produced by CD8+ T cells. Performing-low memory CD8+ T cells that normally synthesize MIP-1-beta. the CCL4 gene was assigned to a slightly more distal location: 17q21-q23 rather than 17q11-q21.
