Background of C1R
Complement C1r subcomponent is a protein involved in the complement system of the innate immune system. It is mapped to 12p13.31. In humans, C1r is encoded by the C1R gene. C1r along with C1q and C1s form the C1 complex, which is the first component of the serum complement system. C1r is an enzyme that activates C1s to its active form, by proteolytic cleavage.C1r has been shown to interact with C1s. C1r cleaves C1s to form the active form of C1s.

Recommended Sample Dilution Ratios
According to our internal validation assays using this ELISA kit, to detect C1R, Dilution ratio of 1:500, concentration in serum and plasma is around 10 ug/ml..
Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Human Complement C1R 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.

5 Customer Q&As for Human Complement C1R ELISA Kit PicoKine®
Question
Q: is it okay to use EDTA plasma as samples in Human Complement Component C1r Picokine® ELISA Kit (Catalog # EK1954)?
D. Mitchell
Verified customer
Asked: 2020-08-23
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can irreversibly bind metal ions from the functional domain of Complement Component C1r causing disruption of its protein structure. Complement Component C1r 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 Complement Component C1r ELISA, treating samples with different anticoagulants and decided that heparin, EDTA or citrate 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?
Verified Customer
Verified customer
Asked: 2020-08-03
Answer
A: for 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 may impact immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Question
Q: Are Boster Bio recombinant proteins and antibodies sterile?
S. Allen
Verified customer
Asked: 2019-02-11
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 needed for an experiment, the material can be filtered through a 0.2 micron filter designed for use with biological fluids.

Question
Q: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for measurement Complement Component C1r using the EK1954 Human Complement Component C1r Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2017-02-26
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 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 limit protein degradation.

Question
Q: Can Complement Component C1r ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
Verified Customer
Verified customer
Asked: 2014-10-09
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 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 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 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.
