Background of Relaxin-1
Relaxin 1 is a member of relaxin-like peptide family. Relaxin gene maps to human chromosome 19 near D19Mit23. Relaxin is a peptide hormone produced by the corpora lutea of ovaries during pregnancy in many mammalian species, including man. Relaxin widens the pubic bone and facilitates labor, it also softens the cervix (cervical ripening), and relaxes the uterine musculature. However, its significance may reach much further. Relaxin affects collagen metabolism, inhibiting collagen synthesis and enhancing its breakdown by increasing matrix metalloproteinases. It also enhances angiogenesis and is a potent renal vasodilator.

Question
Q: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for analysis Relaxin-1 using the EK1230 Human Relaxin-1 Picokine® ELISA Kit?
T. Evans
Verified customer
Asked: 2020-11-10
Answer
A: Boster Bio does not assess sample stability. Variations in sample collection, processing, and storage may change 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 to limit protein degradation.

Question
Q: how to thaw whole blood sample for Relaxin-1 ELISA after freezing?
Verified Customer
Verified customer
Asked: 2019-07-29
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 Relaxin-1 for a later time, you should let the blood clot in glass tubes and separate the serum to freeze for later analysis.

Question
Q: how are cell lysates prepared for use in Picokine® ELISA kits?
A. Jha
Verified customer
Asked: 2018-11-25
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 can effect immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Question
Q: Can Relaxin-1 ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
Verified Customer
Verified customer
Asked: 2018-03-05
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 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. 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 Relaxin-1 in Human plasma? I am trying to measure a a number of 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: 2018-03-02
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 Relaxin-1 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 Relaxin-1 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 Relaxin-1 antigen?
Verified Customer
Verified customer
Asked: 2016-04-17
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.
