Background of Complement Factor H
Complement factor H (CFH), originally known as beta-1H globulin, is a serum glycoprotein that regulates the function of the alternativecomplement pathway in fluid phase and on cellular surfaces. It binds to C3b, accelerates the decay of the alternative pathway convertase C3bBb, and also acts as a cofactor for complement factor I, another C3b inhibitor. The CFH gene is located on chromosome 1q32-q32.1 within a cluster of genes encoding the regulatory complement components of the activation of C3 (RCA for 'regulators of complement activation'). This gene cluster includes decay-accelerating factor (DAF), C4-binding protein (C4BPA and C4BPB), and the factor H-related genes CFHR1, CFHR2, CFHR3, CFHR4, and CFHR5, among others. The gene family has arisen by multiple duplication events.

Question
Q: we need your suggestion regarding the dilution ratio of serum samples for detection of Complement Factor H in Mouse plasma? I am trying to measure a few parameters and it requires 100ul of diluted samples for each well. We have low serum quantitys so we like to dilute as much as possible.
G. Williams
Verified customer
Asked: 2020-09-11
Answer
A: without knowing the physiological or pathological context of your samples we cannot recommend a dilution ratio without performing a pilot test with your samples. Here is how you can perform a pilot study on your own: perform a serial dilution of your samples on the Complement Factor H ELISA kit to make sure you have a linear ascending curve followed by a plateau, which signifies the samples saturating the detection limit of the kit. Then you can pick the dilution ratios from samples in the linear part of the curve as your experimental dilution ratio.
If you are interested in using our ELISA service, you can also send us your sample and we will take care of everything for you. You can check our service details here: bosterbio.com/services/assay-services/ELISA-testing-service
Since you mentioned you have limited samples, our cost effective multiplex ELISA service would fit perfectly for your needs, where we can generate dozens of data points using as little as 25ul sample volume. Information on this service is also in the above link.

Question
Q: if the enzyme conjugated Complement Factor H antibodies are mixed with the substrate, will that convert the substrate into the enzymatic reaction product? Or the enzyme function is only activated when the antibody is attached with the Complement Factor H antigen?
Verified Customer
Verified customer
Asked: 2020-07-18
Answer
A: The enzyme is always active. Avoid contaminating the substrate with enzyme prior to the incubation otherwise it compromises the assay with false positive signal.

Question
Q: is it okay to use citrate plasma as samples in Mouse Complement Factor H Picokine® ELISA Kit (Catalog # EK1400)?
Verified Customer
Verified customer
Asked: 2020-06-28
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can irreversibly bind metal ions from the functional domain of Complement Factor H causing degradation of its protein structure. Complement Factor H may be denatured as a result and may compromise the assay's measurements. The chilating sites could also be too close to the epitopes a must for detection and block the antigen antibody reaction. We have tested the Complement Factor H 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: how can I thaw whole blood sample for Complement Factor H ELISA after freezing?
Verified Customer
Verified customer
Asked: 2020-01-10
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 Complement Factor H 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 optimal O.D. value for Complement Factor H ELISA kit? I used your Complement Factor H 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 H even though the O.D. values are not very high?
Z. Zhao
Verified customer
Asked: 2019-06-03
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. a point of focus should be is whether your sample O.D. values are statistically significantly higher than your blank values. in the above example, 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 proportion to your positive controls. normally, 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 H ELISA kit to have sensitivity of 20pg/ml, that means the minimum amount of Complement Factor H that can be declared/interpreted as positive by the above standard is 20pg/ml.

Asked: 2016-11-27
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 a must for an experiment, the material can be filtered through a 0.2 micron filter designed for use with biological fluids.

Question
Q: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for measurement Complement Factor H using the EK1400 Mouse Complement Factor H Picokine® ELISA Kit?
L. Kumar
Verified customer
Asked: 2016-06-26
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 right 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 prevent protein degradation.

Question
Q: Can Complement Factor H ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
Verified Customer
Verified customer
Asked: 2016-03-19
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.
