Human Lymphocyte Function Associated Antigen 1 Alpha (LFA1a) ELISA Kit
The Human Lymphocyte Function-Associated Antigen-1 Alpha (LFA1a) ELISA Kit is a powerful tool for detecting levels of LFA1a in human samples such as serum, plasma, and cell culture supernatants. This kit offers outstanding sensitivity and specificity, ensuring consistent and accurate results for a variety of research applications.LFA1a is a crucial protein involved in immune system function, specifically in regulating lymphocyte adhesion and activation.
Dysregulation of LFA1a has been linked to various autoimmune diseases, inflammatory disorders, and immune deficiencies, making it a valuable biomarker for studying these conditions and developing potential therapies.With its high-performance capabilities, the Human Lymphocyte Function-Associated Antigen-1 Alpha ELISA Kit is an essential tool for researchers looking to investigate the role of LFA1a in immune responses and related diseases.

Intra-assay Precision:
Intra-Assay: CV <10%. 3 samples with low, middle and high level the index were tested 20 times on one plate, respectively.
Inter-assay Precision:
Inter-Assay: CV <12%. 3 samples with low, middle and high level the index were tested on 3 different plates, 8 replicates in each plate.
Stability:
The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage conditions. Note: To minimize unnecessary influences on the performance, operation procedures and lab conditions, especially room temperature, air humidity and incubator temperatures should be strictly regulated. It is also strongly suggested that the whole assay is performed by the same experimenter from the beginning to the end.
