Background of Activin A
Activin A is a homodimer of 14kDa beta-A. Activin A, a cytokine member of the transforming growth factor-beta superfamily, is expressed locally by the mesenchymal component of the hemopoietic microenvironment. Its expression is regulated on the mRNA level by different cytokines, and the biological activity of the protein is tightly controlled by several inhibitory molecules. Inhibins and activins are members of the transforming growth factor beta superfamily and are known to modulate the growth and differentiation of several cell types. Inhibins and activins inhibit and activate, respectively, the secretion of follitropin by the pituitary gland. Inhibins/activins are involved in regulating a number of diverse functions such as hypothalamic and pituitary hormone secretion, gonadal hormone secretion, germ cell development and maturation, erythroid differentiation, insulin secretion, nerve cell survival, embryonic axial development or bone growth, depending on their subunit composition. Inhibins appear to oppose the functions of activins. The standard product used in this kit is recombinant Activin A, which is composed of two single chains of 116 amino acids with the molecular mass of 26KDa.

6 Customer Q&As for Monkey primate Activin A ELISA Kit PicoKine®
Question
Q: Are Boster Bio recombinant proteins and antibodies sterile?
Verified Customer
Verified customer
Asked: 2020-11-04
Answer
A: although the vials are bottled using aseptic techniques, heat-treated vials, and sterile stock solutions, they are not considered or guaranteed to be sterile. If sterile material is required for an experiment, the material can be filtered through a 0.2 micron filter designed for use with biological fluids.

Question
Q: Can Activin A ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
B. Anand
Verified customer
Asked: 2020-09-17
Answer
A: Unfortunately, Boster Bio has not routinely validated tissue homogenates as a sample type for ELISA kits. This does not mean that ELISA kits are not valid for other sample types than we have tested: it means further investigation is required. One will need to perform a spike and recovery study to determine if an unvalidated sample type will work with a particular kit. To perform a spike and recovery experiment, one should divide a sample into two aliquots. In one of the aliquots, the user should spike in a known amount of the kit standard. a dilution series is performed comparing the spiked versus the unspiked sample. Generally, samples with expected recovery and linearity between 80-120% are considered acceptable. This method can be used to validate any sample type that has not been assessd by Boster Bio. for a more detailed spike and recovery protocol, please contact technical support.
Note: acceptable ranges should be determined individually by each laboratory. Additionally, technical support can help determine if a buffer component is not compatible with a given ELISA kit. please see the Citations tab on the product webpage for peer-reviewed papers utilizing a wide range of sample types. We also have an innovator's reward program where if the user validates our ELISA kits in applications or samples previously not validated by Boster Bio or other users, and share such information with us by submit a review, we will reward the user's efforts with a free antibody or ELISA kit from our catalog. Biocompare.com will also give $20 Amazon giftcard as an additional reward, if the review is submitted there as well.

Question
Q: if the enzyme conjugated Activin A antibodies are mixed with the substrate, will that change the substrate into the enzymatic reaction product? Or the enzyme function is only activated when the antibody is attached with the Activin A antigen?
S. Thompson
Verified customer
Asked: 2020-04-12
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.

Question
Q: how to thaw whole blood sample for Activin A ELISA after freezing?
T. Phillips
Verified customer
Asked: 2020-01-14
Answer
A: we do not recommend freezing 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 Activin A for a later time, you should let the blood clot in glass tubes and separate the serum to freeze for later analysis.

Question
Q: is it okay to use citrate plasma as samples in Monkey Activin A Picokine® ELISA Kit (Catalog # EK0301-PR)?
Verified Customer
Verified customer
Asked: 2019-06-02
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can attach metal ions from the functional domain of Activin A causing disruption of its protein structure. Activin A may be denatured as a result and may compromise the assay's measurements. The chilating sites could also be too close to the epitopes required for detection and block the antigen antibody reaction. We have tested the Activin A ELISA, treating samples with different anticoagulants and decided that heparin or EDTA can be used for treatment of blood/plasma samples. Do not use other anticoagulents when collecting samples.

Question
Q: What is the optimal O.D. value for Activin A ELISA kit? I used your Activin A ELISA on serum samples. For my positive control, I received an O.D. value of 0.826, while my negative control received a value of 0.136. I obtained both of these controls from the ELISA kit, where your kit's typical data shows O.D. values much higher than my positive control and your background is lower. My samples O.D. values are around 0.225 and the highest is only 0.357. can I consider these samples contain Activin A even though the O.D. values are not very high?
Verified Customer
Verified customer
Asked: 2018-05-28
Answer
A: The absolute O.D. values may change according to incubation time. The more you incubate the higher the O.D. values are going to be. a point of focus should be is whether your sample O.D. values are statistically significantly higher than your blank values. in the above example, you could extend your development time in the substrate incubation step to obtain higher O.D. values, as long as your negative controls' O.D. values are not increasing faster in proportion to your positive controls. normally, a sample with O.D. value 2 standard deviations higher than your negative controls can be considered positive. We calculate the sensitivity of this ELISA kit by changeing cutoff O.D. value, calculated as the average of 20 negative controls plus 2 standard deviations of the 20 negative controls, into a concentration. in other words, when we claim this Activin A ELISA kit to have sensitivity of 12pg/ml, that means the minimum amount of Activin A that can be declared/interpreted as positive by the above standard is 12pg/ml.
