Human Heparan Sulfate Proteoglycan (HSPG) ELISA Kit
The Human Heparan Sulfate Proteoglycan (HSPG) ELISA Kit is a powerful tool for the precise measurement of HSPG levels in human biological samples such as serum, plasma, and cell culture supernatants. With its exceptional sensitivity and specificity, this kit delivers accurate and consistent results that are essential for various research applications.HSPG is a critical component of the extracellular matrix that plays a key role in cell adhesion, growth factor signaling, and tissue development. Dysregulation of HSPG expression has been linked to various diseases, including cancer, diabetes, and inflammatory disorders.
By accurately quantifying HSPG levels, researchers can gain valuable insights into disease mechanisms and potential therapeutic targets.The Human Heparan Sulfate Proteoglycan (HSPG) ELISA Kit is a valuable tool for studying the biology of HSPG and its implications in health and disease. Its reliability and precision make it an indispensable asset for researchers seeking to uncover the role of HSPG in various physiological and pathological processes.

Linearity:
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of the index and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

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.
