Background of Complement Factor D/Adipsin
Complement factor D (CFD), also called ADIPSIN or FACTOR D, is a protein which in humans is encoded by the CFD gene. The protein encoded by this gene belongs to the trypsin family of peptidases. It is mapped to 19p13.3. The encoded protein is a component of the alternative complement pathway which is best known for its role in humoral suppression of infectious agents. This protein is also a serine protease that is secreted by adipocytes into the bloodstream. Finally, the encoded protein has a high level of expression in fat, suggesting a role for adipose tissue in immune system biology. What’s more, Factor D is a serine protease that stimulates glucose transport for triglyceride accumulation in fats cells and inhibits lipolysis.

Pretty good product with a reasonable price--Xiaobing Cui, University of Georgia, Physiology & Pharmacology, Research Scientist

| Sample | Serum and supernatant |
| Detection | -- |
"I did this assay twice. Both times were very good. First time I diluted the mouse serum and cell culture supernatant for 100-fold. However, the values of the serum are out of the range of standards. Then, I repeated the assay by diluting the mouse serum for 3000-fold. Much better than the 1st time, but still some values are marginally out of the range of standards. It is recommended that to do a dilution test using small amount of samples. Generally, you can get a very good result, just follow the instruction of this product. Easy to use. Good quality of data. It is a pretty good product with a reasonable price." (Customer’s Tip: "The serum needs to be diluted 5000-fold. The supernatant needs to be diluted 100-fold. Incubate for 10-15 min is enough after adding Color Developing Reagent.")

Q: Are Boster Bio recombinant proteins and antibodies sterile?
Verified Customer
Verified customer
Asked: 2020-04-06
Answer
A: although the vials are bottled using aseptic techniques, heat-treated vials, and sterile stock solutions, they are not considered or guaranteed to be sterile. If sterile material is required for an experiment, the material can be filtered through a 0.2 micron filter designed for use with biological fluids.

Question
Q: can you tell me how to prepare cell lysates prepared for use in Picokine® ELISA kits?
Verified Customer
Verified customer
Asked: 2020-03-27
Answer
A: for those Picokine® ELISAs where cell or tissue lysate is a validated sample type, sample preparation instructions for lysate can be found in the product insert. Components in lysate and lysis buffer may impact immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Question
Q: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for measuring Complement Factor D using the EK1420 Mouse Complement Factor D Picokine® ELISA Kit?
R. Taylor
Verified customer
Asked: 2019-04-20
Answer
A: Boster Bio does not evaluate sample stability. Variations in sample collection, processing, and storage may affect 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 repetitive freeze-thaw cycles with the stored samples in order to limit protein degradation.

Question
Q: how to thaw whole blood sample for Complement Factor D ELISA after freezing?
Y. Thomas
Verified customer
Asked: 2019-02-09
Answer
A: do not freeze 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 Complement Factor D for a later time, you should let the blood clot in glass tubes and collect the serum to freeze for later use.

Question
Q: What is the optimal O.D. value for Complement Factor D ELISA kit? I performed your Complement Factor D ELISA on serum samples. For my positive control, I received an O.D. value of 0.826, while my negative control received a value of 0.136. I obtained both of these controls from the ELISA kit, where your kit's typical data shows O.D. values much higher than my positive control and your background is lower. My samples O.D. values are around 0.225 and the highest is only 0.357. can I consider these samples contain Complement Factor D even though the O.D. values are not very high?
Verified Customer
Verified customer
Asked: 2018-08-27
Answer
A: The absolute O.D. values may change according to incubation time. The more you incubate the higher the O.D. values are going to be. what you should focus on is whether your sample O.D. values are statistically significantly higher than your blank values. in the example mentioned, you could extend your development time in the substrate incubation step to obtain higher O.D. values, as long as your negative controls' O.D. values are not increasing faster in relation to your positive controls. typically, a sample with O.D. value 2 standard deviations higher than your negative controls can be considered positive. We calculate the sensitivity of this ELISA kit by changeing cutoff O.D. value, calculated as the average of 20 negative controls plus 2 standard deviations of the 20 negative controls, into a concentration. in other words, when we claim this Complement Factor D ELISA kit to have sensitivity of 20pg/ml, that means the minimum amount of Complement Factor D that can be declared/interpreted as positive by the above standard is 20pg/ml.

Question
Q: Can Complement Factor D ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
A. Walker
Verified customer
Asked: 2018-04-10
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 valid for other sample types than we have tested: it means further investigation is needed. 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 evaluated 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 view 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.
