Background of Marapsin/Pancreasin
Pancreasin, also known as PRSS27 or Marapsin, is a pancreatic tryptic serine peptidase that cleaves peptides after an arginine residue. It belongs to the group-1 subfamily of serine proteases. The pancreasin gene is mapped to chromosome 16p13.3. Pancreasin is resistant to inactivation by large molecular mass trypsin inhibitors, but it is sensitive to benzamidine and leupeptin.

Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Mouse Marapsin/Pancresin 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.

Question
Q: how can I thaw whole blood sample for Marapsin ELISA after freezing?
Verified Customer
Verified customer
Asked: 2020-05-08
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 Marapsin for a later time, you should let the blood clot in glass tubes and separate the serum to freeze for later analysis.

Question
Q: What is the optimal O.D. value for Marapsin ELISA kit? I used your Marapsin 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 Marapsin even though the O.D. values are not very high?
V. Banerjee
Verified customer
Asked: 2018-09-14
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. regarding your assay, 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. 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 Marapsin ELISA kit to have sensitivity of 10pg/ml, that means the minimum amount of Marapsin that can be declared/interpreted as positive by the above standard is 10pg/ml.

Question
Q: Are Boster Bio recombinant proteins and antibodies sterile?
W. Banerjee
Verified customer
Asked: 2018-07-26
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: if the enzyme conjugated Marapsin 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 Marapsin antigen?
C. Huang
Verified customer
Asked: 2017-08-31
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.

Question
Q: how many samples can be assayed in a Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2016-03-29
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 depends upon the kit used so please refer to each datasheet for details.

Question
Q: Can Marapsin ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
Verified Customer
Verified customer
Asked: 2014-11-29
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.
