Human activin a duoset elisa kit

Manufactured by R&D Systems

The Human activin-A duoset ELISA kit is a tool used to detect and quantify the presence of the protein activin-A in human samples. It is a sandwich enzyme-linked immunosorbent assay (ELISA) that utilizes two specific antibodies to capture and detect the target analyte. The kit provides the necessary reagents and instructions to perform this assay.

Activin-A was measured in undiluted decidual culture supernatants (n = 11) using the human activin-A duoset ELISA kit (R&D Systems) as per the manufacturer’s protocol. The concentrations were calculated in picogram per milliliter and corrected for the number of live cells per treatment group. Total STAT3 was measured in decidual cell lysates (n = 8) using the human STAT3 ELISA kit (Abcam ab176666) as per the manufacturer’s protocol. Cell lysates were prepared from 2 × 106 cells per treatment group and were in the range of 100–500 µg/ml of total protein. Lysates were aliquoted and stored at −80°C and assayed within a month. Total STAT3 concentrations were calculated in microgram per milliliter, corrected for total protein concentration per treatment group, and normalized to the control, which was set at 100%.

Quantification of Activin A in Cell Clusters

Check if the same lab product or an alternative is used in the 5 most similar protocols
Conditional media from the cell clusters isolated from 4‐week‐old control or KC mice were used for mouse cytokines analysis using RayBio Mouse Biotin‐Label Based Antibody Array (Mouse L‐308 Array, Glass Slide). For mouse Activin A quantification, Activin A in conditional media or serum was detected using the Human/Mouse/Rat Activin A Quantikine ELISA Kit (R&D Systems #DAC00B). For human Activin A quantification, Activin A in HPDE conditional media was detected using Human Activin a DuoSet ELISA Kit (R&D Systems #DY338). The amount of Activin A was normalized to the total protein in conditional media or sera and represented as pg mg−1.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
