Background of CREG
Protein CREG1 (Cellular Repressor of E1A-stimulated Genes 1) is a protein that in humans is encoded by the CREG1 gene. It is mapped to 1; 1 H2.3. The adenovirus E1A protein both activates and represses gene expression to promote cellular proliferation and inhibit differentiation. The protein encoded by this gene antagonizes transcriptional activation and cellular transformation by E1A. This protein shares limited sequence similarity with E1A and binds both the general transcription factor TBP and the tumor suppressor pRb in vitro. This gene may contribute to the transcriptional control of cell growth and differentiation.

Question
Q: Can CREG ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
Verified Customer
Verified customer
Asked: 2020-08-24
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.

Question
Q: can you recommend the dilution ratio of serum samples for detection of CREG in Mouse plasma? I am trying to measure a few analytes and it requires 100ul of diluted samples for each well. We have limited sample quantitys so we like to dilute as much as possible.
Verified Customer
Verified customer
Asked: 2019-11-21
Answer
A: unable to know 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 CREG 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: is it okay to use citrate plasma as samples in Mouse CREG Picokine® ELISA Kit (Catalog # EK1950)?
Verified Customer
Verified customer
Asked: 2019-04-06
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can bind metal ions from the functional domain of CREG causing degradation of its protein structure. CREG 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 CREG ELISA, treating samples with a number of anticoagulants and decided that heparin can be used for treatment of blood/plasma samples. Do not use other anticoagulents when collecting samples.

Question
Q: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for measurement CREG using the EK1950 Mouse CREG Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2018-02-06
Answer
A: Boster Bio does not assess 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 prevent protein degradation.

Question
Q: which procedure should I follow in order to thaw whole blood sample for CREG ELISA after freezing?
A. Dayal
Verified customer
Asked: 2017-07-21
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 CREG for a later time, you should let the blood clot in glass tubes and collect the serum to freeze for later use.
