Intra-assay Precision (Precision within an assay): CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.
To assess the linearity of the assay, samples were spiked with high concentrations of human ECP in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Q&A and Customer Reviews


I am interested in your Human eosinophil Cationic protein, ECP ELISA Kit (CSB-E11729h). However, I will test other markers and need advide for collection/preparation for this kit as stated below:
“I am hoping to get some information about the collection/preparation of serum prior to analysis. My lab will be analyzing serum samples for a variety of markers. the other markers all state to allow clotting for 30 minutes prior to centrifugation. The ECP (human) kit that I am interested in states to allow clotting for 2 hours. I was wondering if you could tell me if it needs to sit for two hours, or if 30 minutes if suffice. We are trying to avoid needed to process two separate samples so i'm hoping you can help me!”

Thanks for your inquiry.
This kit can test serum and plasma samples. For serum samples, usually we will keep it static for 2 hours and then collect it. In this way more samples can be precipitated. What's more, if the static time is enough, the fibrin can timely trap hematocyte and then shrink and sink. Then if we treat it by centrifugation, the fibrin will not stay in the serum.
As it is mentioned, static for 30 minutes, we think that this static time is not very sufficient, and coagulation phenomenon is not very obvious. It is recommended to extend the static time. Later you should be able to see obvious coagulation and then extend the time. In this way more samples can be precipitated.
Pls let me know if you have any further questions. Thank you.

Target Data

Function Cytotoxin and helminthotoxin with low-efficiency ribonuclease activity. Possesses a wide variety of biological activities. Exhibits antibacterial activity, including cytoplasmic membrane depolarization of preferentially Gram-negative, but also Gram-positive strains. Promotes E.coli outer membrane detachment, alteration of the overall cell shape and partial loss of cell content.
Subcellular Location Secreted
Protein Families Pancreatic ribonuclease family
