Rat Surfactant Associated Protein D (SPD) ELISA Kit
The Rat Surfactant Associated Protein D (SP-D) ELISA Kit is specifically designed for the accurate quantification of SP-D levels in rat serum, plasma, and cell culture supernatants. This kit offers high sensitivity and specificity, ensuring precise and reproducible results for a variety of research applications.SP-D is an important protein involved in pulmonary surfactant function, playing a key role in lung immunity and defense against respiratory infections. Dysregulation of SP-D levels is associated with various pulmonary diseases, including acute respiratory distress syndrome (ARDS) and chronic obstructive pulmonary disease (COPD), making it a valuable biomarker for studying these conditions and potential therapeutic interventions.
Overall, the Rat SP-D ELISA Kit provides researchers with a reliable tool for studying the role of SP-D in pulmonary health and disease, offering valuable insights into respiratory conditions and potential treatment strategies.

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.
