Background of CD163
CD163 (Cluster of Differentiation 163) is a human protein encoded by the CD163 gene. It has also been shown to mark cells of monocyte/macrophage lineage. CD163, a member of the scavenger receptor cysteine-rich (SRCR) superfamily, is exclusively expressed by monocytes and macrophages. Using FISH, somatic cell hybrid analysis, and radiation hybrid analysis, CD163 gene was mapped the to chromosome 12p13.3. CD163 is upregulated in a large range of diseases inflammatory diseases including type 2 diabetes, macrophage activation sickness, Tangier's disease, reumatoid arthritis etc.

Question
Q: Can CD163 ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
T. Green
Verified customer
Asked: 2020-10-27
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 required. 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 see 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: What is the optimal O.D. value for CD163 ELISA kit? I used your CD163 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 CD163 even though the O.D. values are not very high?
Verified Customer
Verified customer
Asked: 2020-10-16
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. an important assessment should be is whether your sample O.D. values are statistically significantly higher than your blank values. in your 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 CD163 ELISA kit to have sensitivity of 150pg/ml, that means the minimum amount of CD163 that can be declared/interpreted as positive by the above standard is 150pg/ml.

Question
Q: how to thaw whole blood sample for CD163 ELISA after freezing?
P. Adams
Verified customer
Asked: 2020-09-27
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 CD163 for a later time, you should let the blood clot in glass tubes and collect the serum to freeze for later use.

Question
Q: Are Boster Bio recombinant proteins and antibodies sterile?
M. Hill
Verified customer
Asked: 2020-09-14
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
Could EDTA be used as an anticoagulant to collect plasma samples or do you advise to stick with the procedure in the EK0715 manual?
Verified customer
Asked: 2020-06-17
Answer
Usually we advise to follow the manual because EDTA plasma has chelating properties and may negatively affect results using the HSP70 ELISA Kit (High-Sensitivity) (EK7109).

Question
Q: how many samples can be assayed in a Picokine® ELISA Kit?
A. Jackson
Verified customer
Asked: 2019-07-17
Answer
A: The Picokine® ELISA Kits will generally run a 7-point standard curve, non-specific binding wells, and 39 samples in duplicate. this may might differ by kit so please refer to each datasheet for details.

Question
Q: can I use EDTA plasma as samples in Human CD163 Picokine® ELISA Kit (Catalog # EK0715)?
Verified Customer
Verified customer
Asked: 2018-09-01
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can attach metal ions from the functional domain of CD163 causing degradation of its protein structure. CD163 may be denatured as a result and may compromise the assay's measurements. The chilating sites could also be too close to the epitopes required for detection and block the antigen antibody reaction. We have tested the CD163 ELISA, treating samples with various anticoagulants and decided that heparin can be used for treatment of blood/plasma samples. Do not use other anticoagulents when collecting samples.

Question
Q: what is the protocol regarding preparation of cell lysates prepared for use in Picokine® ELISA kits?
B. Chakrabarti
Verified customer
Asked: 2018-05-14
Answer
A: for those Picokine® ELISAs where cell or tissue lysate is a validated sample type, sample preparation instructions for lysate are included 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.
