Key=background, value=Myostatin (also known as growth differentiation factor 8, abbreviated GDF-8) is a myokine, a protein produced and released by myocytes that acts on muscle cells' autocrine function to inhibit myogenesis: muscle cell growth and differentiation. In humans it is encoded by the MSTN gene. It is mapped to 1 C1.1; 1 26.99 cM. Myostatin is a secreted growth differentiation factor that is a member of the TGF beta protein family. This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. The encoded preproprotein is proteolytically processed to generate each subunit of the disulfide-linked homodimer. This protein negatively regulates skeletal muscle cell proliferation and differentiation. Mutations in this gene are associated with increased skeletal muscle mass in humans and other mammals.

Question

Q: can you recommend the dilution ratio of serum samples for detection of GDF-8 in Mouse plasma? I am trying to measure a few analytes and it requires 100ul of diluted samples for each well. We have low serum quantitys so we like to dilute as much as possible.

Verified Customer

Verified customer

Asked: 2020-04-17

Answer

A: without having an understanding the physiological or pathological context of your samples we cannot recommend a dilution ratio without performing a pilot test with your samples. Here is how you can perform a pilot study on your own: perform a serial dilution of your samples on the GDF-8 ELISA kit to make sure you have a linear ascending curve followed by a plateau, which signifies the samples saturating the detection limit of the kit. Then you can pick the dilution ratios from samples in the linear part of the curve as your experimental dilution ratio.
If you are interested in using our ELISA service, you can also send us your sample and we will take care of everything for you. You can check our service details here: bosterbio.com/services/assay-services/ELISA-testing-service
Since you mentioned you have limited samples, our cost effective multiplex ELISA service would fit perfectly for your needs, where we can generate dozens of data points using as little as 25ul sample volume. Information on this service is also in the above link.

Question

Q: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for analysis GDF-8 using the EK1266 Mouse GDF-8 Picokine® ELISA Kit?

A. Sunder

Verified customer

Asked: 2019-07-27

Answer

A: Boster Bio does not assess sample stability. Variations in sample collection, processing, and storage may change the stabilityof samples. It is recommend to assay sample on-stat collection when possible, or aliquot into single use volumes and store samples frozen. avoid repetitive freeze-thaw cycles with the stored samples to limit protein degradation.

Question

Q: how can I thaw whole blood sample for GDF-8 ELISA after freezing?

D. Anderson

Verified customer

Asked: 2018-10-21

Answer

A: do not freeze and thaw whole blood. erythrocytes are fragile and, if frozen and thawed, will undergo hemolysis rendering the samples useless. To keep your blood samples to test GDF-8 for a later time, you should let the blood clot in glass tubes and collect the serum to freeze for later use.

Question

Q: how many samples can be assayed in a Picokine® ELISA Kit?

Verified Customer

Verified customer

Asked: 2016-09-10

Answer

A: The Picokine® ELISA Kits will generally run a 7-point standard curve, non-specific binding wells, and 39 samples in duplicate. this may might differ by kit so please refer to each datasheet for details.

Boster Scientific Support

Answered: 2016-09-10

Question

Q: if the enzyme conjugated GDF-8 antibodies are mixed with the substrate, will that convert the substrate into the enzymatic reaction product? Or the enzyme function is only activated when the antibody is attached with the GDF-8 antigen?

Verified Customer

Verified customer

Asked: 2016-08-06

Answer

A: The enzyme is always active. Avoid contaminating the substrate with enzyme prior to the incubation otherwise it compromises the assay with false positive signal.
