The treatment with acetonitrile removes the matrix effect, including the proteins, from the samples. This means that the cortisol bound to albumin and other proteins is eliminated. The assay specifically measures the free cortisol (non-bound cortisol).

Description générale
Cytokines, chemokines, and growth factors are key mediatorsof immune system functions capable of signaling through autocrine, paracrine,and endocrine mechanisms. Their pleiotropic immunomodulatory propertiesallow these biomolecules to react to diverse stimuli and regulate the immuneresponse, either promoting or inhibiting inflammation.

When precipitating proteins (albumin and globulins) from plasma or serum samples using an Acetonitrile solution, does cortisol, which is bound to albumin & globulin, dissociate into the solution or get removed along with the protein precipitate?

Could you please provide the expected sample ranges for the Milliplex Human Cytokine Panel A (HCYTA-60K)?
1 réponse-
The serum and plasma sample values for the HCYTA-60K kit are provided. It's important to note that these values should be used as a guideline only. This data is based on a small sample size without effort for randomization and is not a true reference range.

Could you provide a recommendation for sample preparation for placenta and HCYTA-60K assay?
1 réponse-
The Milliplex assays have not been tested or verified for use with placenta tissue homogenates. However, a reference is available using placenta homogenates in the Human Cytokine Panel 1 (HCYTOMAG-60K).
The samples were prepared as follows:
Placental homogenate: Fragments of frozen placental tissue were transferred to propylene tubes containing lysis buffer and a cocktail of protease inhibitors. The placenta samples were homogenized using an electric homogenizer on ice. After homogenization, the homogenates were centrifuged, and the protein concentration in the supernatant was measured and stored for further analysis.Reference: Molás RB, Ribeiro MR, Ramalho Dos Santos MJC, et al.

What type of IL-12p40 was detected in the Human Cytokine Panel A (HCYTA-60K) – IL-12p40 monomer or IL-12p40 total (both monomer and homodimer)?
1 réponse-
The capture in the assay detects the IL-12p40 monomer, and the standard used is also the IL-12p40 monomer. However, specific testing has not been conducted to determine if it also detects the homodimer.

Can the Milliplex Human Cytokine/Growth Factor Panel A (HCYTA-60K) measure IFNa2a or IFNA2B?
1 réponse-
Based on the antibody and standard specification sheets, the kit detects both IFNa2a and IFNa2B. The capture antibody is listed as an IFNa2B antibody and does not mention IFNa2a. However, the standard is recombinant IFNa2a.

-
Is it better to use EDTA vacutainers than heparinized vacutainers when collecting blood from plasma? Does this apply to both humans and mice?
1 réponse-
For our Milliplex assays, EDTA plasma is preferred. Care must be taken when using heparin as an anticoagulant since an excess of heparin will provide falsely high values. Use no more than 10 IU heparin per mL of blood collected.
Utile ?
-
-
Is there an alternative method if a bath sonicator is not available for sonication of beads as mentioned in the Milliplex protocols? Can vortexing for a longer period serve as an alternative?
1 réponse-
The Milliplex assays recommend using a sonicator (water bath, Branson B200 or equivalent). Sonication helps break up any aggregated beads and beads stuck to the vial to reduce aggregation and improve counts. If a bath sonicator is not available, you can vortex for up to 2 minutes.
