Background of CD55/DAF
Complement decay-accelerating factor, also known as CD55 or DAF, is a protein that, in humans, is encoded by the CD55 gene. It is mapped to 1 E4; 1 56.89 cM. This gene encodes a glycoprotein involved in the regulation of the complement cascade. Binding of the encoded protein to complement proteins accelerates their decay, thereby disrupting the cascade and preventing damage to host cells. Antigens present on this protein constitute the Cromer blood group system (CROM). Alternative splicing results in multiple transcript variants. The predominant transcript variant encodes a membrane-bound protein, but alternatively spliced transcripts may produce soluble proteins.

Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Mouse CD55 ELISA Kit PicoKine® within the same batch/lot to ensure the consistency of the kits' performances. ELISA intra assay consistency is measured using wells from the same plate/assay kit. ELISA inter assay consistency is measured using wells from different plates from the same batch production/lot.

7 Customer Q&As for Mouse CD55 ELISA Kit PicoKine®
Question
Q: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for measuring CD55 using the EK1949 Mouse CD55 Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2020-10-01
Answer
A: Boster Bio does not evaluate sample stability. Variations in sample collection, processing, and storage may change the stabilityof samples. It is recommend to assay sample immediately after collection when possible, or aliquot into single use volumes and store samples frozen. avoid repeat freeze-thaw cycles with the stored samples to avoid protein degradation.

Question
Q: Can CD55 ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
R. Yang
Verified customer
Asked: 2020-09-21
Answer
A: Unfortunately, Boster Bio has not routinely validated tissue homogenates as a sample type for ELISA kits. This does not mean that ELISA kits are not suitable for other sample types than we have tested: it means further investigation is a must. One will need to perform a spike and recovery study to determine if an unvalidated sample type will work with a particular kit. To perform a spike and recovery experiment, one should divide a sample into two aliquots. In one of the aliquots, the user should spike in a known amount of the kit standard. a dilution series is performed comparing the spiked versus the unspiked sample. Generally, samples with expected recovery and linearity between 80-120% are considered acceptable. This method can be used to validate any sample type that has not been assessd by Boster Bio. for a more detailed spike and recovery protocol, please contact technical support.
Note: acceptable ranges should be determined individually by each laboratory. Additionally, technical support can help determine if a buffer component is not compatible with a given ELISA kit. please check the Citations tab on the product webpage for peer-reviewed papers utilizing a wide range of sample types. We also have an innovator's reward program where if the user validates our ELISA kits in applications or samples previously not validated by Boster Bio or other users, and share such information with us by submit a review, we will reward the user's efforts with a free antibody or ELISA kit from our catalog. Biocompare.com will also give $20 Amazon giftcard as an additional reward, if the review is submitted there as well.

Question
Q: is it okay to use citrate plasma as samples in Mouse CD55 Picokine® ELISA Kit (Catalog # EK1949)?
Verified Customer
Verified customer
Asked: 2018-09-30
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can bind metal ions from the functional domain of CD55 causing degradation of its protein structure. CD55 may be denatured as a result and may compromise the assay's measurements. The chilating sites could also be too close to the epitopes needed for detection and block the antigen antibody reaction. We have tested the CD55 ELISA, treating samples with a number of anticoagulants and decided that heparin or EDTA can be used for treatment of blood/plasma samples. Do not use other anticoagulents when collecting samples.

Question
Q: which procedure should I follow in order to thaw whole blood sample for CD55 ELISA after freezing?
H. Yang
Verified customer
Asked: 2018-07-17
Answer
A: we do not recommend freezing and thaw whole blood. erythrocytes are fragile and, if frozen and thawed, will undergo hemolysis rendering the samples useless. To keep your blood samples to test CD55 for a later time, you should let the blood clot in glass tubes and separate the serum to freeze for later analysis.

Question
Q: what is the protocol regarding preparation of cell lysates prepared for use in Picokine® ELISA kits?
Verified Customer
Verified customer
Asked: 2018-06-15
Answer
A: in those Picokine® ELISAs where cell or tissue lysate is a validated sample type, sample preparation instructions for lysate are present in the product insert. Components in lysate and lysis buffer can have an affect on immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.
