Background of Galectin-2
Galectin-2 is a protein that in humans is encoded by the LGALS2 gene. It is mapped to 22q13.1. The protein encoded by this gene is a soluble beta-galactoside binding lectin. The encoded protein is found as a homodimer and can bind to lymphotoxin-alpha. It has been found that a single-nucleotide polymorphism in Galectin-2 is significantly associated with susceptibility to myocardial infarction. This genetic substitution affects the transcriptional level of Galectin-2 in vitro, potentially leading to altered secretion of LTA, to which Galectin-2 binds, which would then affect the degree of inflammation.

Question
Q: Can Galectin-2 ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
Verified Customer
Verified customer
Asked: 2020-12-18
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 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.

Question
Q: can you recommend the dilution ratio of serum samples for detection of Galectin-2 in Human cell lysates? I am trying to measure a multiple analytes and it requires 100ul of diluted samples for each well. We have low serum volumes so we like to dilute as much as possible.
L. Dayal
Verified customer
Asked: 2020-01-09
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 Galectin-2 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.

Q: Are Boster Bio recombinant proteins and antibodies sterile?
Verified Customer
Verified customer
Asked: 2019-03-01
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
Q: how can I thaw whole blood sample for Galectin-2 ELISA after freezing?
Verified Customer
Verified customer
Asked: 2018-04-14
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 Galectin-2 for a later time, you should let the blood clot in glass tubes and collect the serum to freeze for later use.

Question
Q: how are cell lysates prepared for use in Picokine® ELISA kits?
J. Campbell
Verified customer
Asked: 2015-08-24
Answer
A: in 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 affect immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Question
Q: What is the optimal O.D. value for Galectin-2 ELISA kit? I used your Galectin-2 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 Galectin-2 even though the O.D. values are not very high?
C. Bhatt
Verified customer
Asked: 2015-02-06
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 relation to your positive controls. typically, 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 converting 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 Galectin-2 ELISA kit to have sensitivity of 10pg/ml, that means the minimum amount of Galectin-2 that can be declared/interpreted as positive by the above standard is 10pg/ml.
