Description

Human MIS / AMH ELISA

MIS / AMH bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. MIS / AMH plays a role in Leydig cell differentiation and function and follicular development in adult females. Mutations in MIS / AMH result in persistent Mullerian duct syndrome. The Assay Genie Human MIS / AMH ELISA is a highly sensitive assay for the quantitative measurement of MIS / AMH in serum, blood, plasma, cell culture supernatant and tissue samples.

Protocol

*Note: Protocols are specific to each batch/lot. For the exact instructions please follow the protocol included in your kit.

Before adding to wells, equilibrate the SABC working solution and TMB substrate for at least 30 min at 37°C. When diluting samples and reagents, they must be mixed completely and evenly. It is recommended to plot a standard curve for each test.

Step Procedure

1.

Set standard, test sample and control (zero) wells on the pre-coated plate respectively, and then, record their positions. It is recommended to measure each standard and sample in duplicate. Wash plate 2 times before adding standard, sample and control (zero) wells!

2.

Aliquot 0.1ml standard solutions into the standard wells.

3.

Add 0.1 ml of Sample / Standard dilution buffer into the control (zero) well.

4.

Add 0.1 ml of properly diluted sample ( Human serum, plasma, tissue homogenates and other biological fluids.) into test sample wells.

5.

Seal the plate with a cover and incubate at 37 °C for 90 min.

6.

Remove the cover and discard the plate content, clap the plate on the absorbent filter papers or other absorbent material. Do NOT let the wells completely dry at any time. Wash plate X2.

7.

Add 0.1 ml of Biotin- detection antibody working solution into the above wells (standard, test sample & zero wells). Add the solution at the bottom of each well without touching the side wall.

8.

Seal the plate with a cover and incubate at 37°C for 60 min.

9.

Remove the cover, and wash plate 3 times with Wash buffer. Let wash buffer rest in wells for 1 min between each wash.

10.

Add 0.1 ml of SABC working solution into each well, cover the plate and incubate at 37°C for 30 min.

11.

Remove the cover and wash plate 5 times with Wash buffer, and each time let the wash buffer stay in the wells for 1-2 min.

12.

Add 90 µl of TMB substrate into each well, cover the plate and incubate at 37°C in dark within 10-20 min. (Note: This incubation time is for reference use only, the optimal time should be determined by end user.) And the shades of blue can be seen in the first 3-4 wells (with most concentrated standard solutions), the other wells show no obvious color.

13.

Add 50 µl of Stop solution into each well and mix thoroughly. The color changes into yellow immediately.

14.

Read the O.D. absorbance at 450 nm in a microplate reader immediately after adding the stop solution.

Sample Type

When carrying out an ELISA assay it is important to prepare your samples in order to achieve the best possible results. Below we have a list of procedures for the preparation of samples for different sample types.

Sample Type Protocol

Serum

If using serum separator tubes, allow samples to clot for 30 minutes at room temperature. Centrifuge for 10 minutes at 1,000x g. Collect the serum fraction and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles.

If serum separator tubes are not being used, allow samples to clot overnight at 2-8°C. Centrifuge for 10 minutes at 1,000x g. Remove serum and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles.

Plasma

Collect plasma using EDTA or heparin as an anticoagulant. Centrifuge samples at 4°C for 15 mins at 1000 × g within 30 mins of collection. Collect the plasma fraction and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles. Note: Over haemolysed samples are not suitable for use with this kit.

Urine & Cerebrospinal Fluid

Collect the urine (mid-stream) in a sterile container, centrifuge for 20 mins at 2000-3000 rpm. Remove supernatant and assay immediately. If any precipitation is detected, repeat the centrifugation step. A similar protocol can be used for cerebrospinal fluid.

Cell culture supernatant

Collect the cell culture media by pipette, followed by centrifugation at 4°C for 20 mins at 1500 rpm. Collect the clear supernatant and assay immediately.

Cell lysates

Solubilize cells in lysis buffer and allow to sit on ice for 30 minutes. Centrifuge tubes at 14,000 x g for 5 minutes to remove insoluble material. Aliquot the supernatant into a new tube and discard the remaining whole cell extract. Quantify total protein concentration using a total protein assay. Assay immediately or aliquot and store at ≤ -20 °C.

Tissue homogenates

The preparation of tissue homogenates will vary depending upon tissue type. Rinse tissue with 1X PBS to remove excess blood & homogenize in 20ml of 1X PBS (including protease inhibitors) and store overnight at ≤ -20°C. Two freeze-thaw cycles are required to break the cell membranes. To further disrupt the cell membranes you can sonicate the samples. Centrifuge homogenates for 5 mins at 5000xg. Remove the supernatant and assay immediately or aliquot and store at -20°C or -80°C.

Tissue lysates

Rinse tissue with PBS, cut into 1-2 mm pieces, and homogenize with a tissue homogenizer in PBS. Add an equal volume of RIPA buffer containing protease inhibitors and lyse tissues at room temperature for 30 minutes with gentle agitation. Centrifuge to remove debris. Quantify total protein concentration using a total protein assay. Assay immediately or aliquot and store at ≤ -20 °C

Breast Milk

Collect milk samples and centrifuge at 10,000 x g for 60 min at 4°C. Aliquot the supernatant and assay. For long term use, store samples at -80°C. Minimize freeze/thaw cycles.

MIS/AMH

Mullerian inhibiting Substance (MIS) / Anti-Mullerian hormone (AMH)

MIS/AMH (Müllerian inhibiting substance/anti-Müllerian hormone) is a protein that plays a crucial role in the development of the reproductive system in both males and females. During fetal development, MIS/AMH is produced by the Sertoli cells in the testes of male embryos. It functions by suppressing the development of the Müllerian ducts, which are responsible for the formation of the uterus, fallopian tubes, and upper vagina in females. The presence of MIS/AMH causes regression of the Müllerian ducts in males, leading to the development of male reproductive organs. In females, MIS/AMH is produced by the granulosa cells of the ovarian follicles. Its expression is highest during the pre-antral and early antral stages of follicle development.

MIS/AMH Structure

AMH, also known as Müllerian-inhibiting substance (MIS), belongs to the TGF-β superfamily. It is a glycoprotein consisting of two identical subunits held together by disulfide bonds, forming a homodimeric structure. With a molecular weight of 140 kDa, AMH is a disulfide-linked protein. The gene encoding AMH is located on the short arm of chromosome 19 in humans, specifically on band 19p13·3. It spans 2750 base pairs and is divided into five exons. The bioactive region of AMH is encoded by the 3' portion of the fifth exon, which is notably GC rich. During development, AMH is highly expressed in Sertoli cells from testicular differentiation through puberty. It is also expressed to a lesser extent in granulosa cells from birth until menopause.

MIS/AMH Levels  

AMH levels can vary depending on age. In women, AMH levels typically begin to increase during adolescence and reach their peak around the age of 25. Subsequently, it is natural for AMH levels to gradually decline. When measuring AMH levels, healthcare providers typically use nanograms per milliliter (ng/mL) as the unit of measurement. While there is ongoing debate among experts regarding the definition of typical AMH levels, there are some general ranges that can be considered. On average, AMH levels can fall within the range of 1.0 ng/mL to 3.0 ng/mL. Levels below 1.0 ng/mL are considered low, and a level of 0.4 ng/mL is classified as severely low. It is important to note that slight variations in results may occur between different laboratories due to the use of different equipment and testing methods.
