Background of Testican 1/SPOCK1
Testican-1 is a protein that in humans is encoded by the SPOCK1 gene. It is mapped to 5q31.2. This gene encodes the protein core of a seminal plasma proteoglycan containing chondroitin- and heparan-sulfate chains. The protein's function is unknown, although similarity to thyropin-type cysteine protease-inhibitors suggests its function may be related to protease inhibition.

According to our internal validation assays using this ELISA kit, to detect Testican 1/SPOCK1, Dilution ratio of 1:1, concentration in serum and plasma is less than the lowest standard, 15.6 pg/ml..
Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Human SPOCK1/Testican-1 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: if the enzyme conjugated Testican 1 antibodies are mixed with the substrate, will that change the substrate into the enzymatic reaction product? Or the enzyme function is only activated when the antibody is attached with the Testican 1 antigen?
Verified Customer
Verified customer
Asked: 2020-08-03
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: What is the optimal O.D. value for Testican 1 ELISA kit? I used your Testican 1 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. is it safe to say these samples contain Testican 1 even though the O.D. values are not very high?
Verified Customer
Verified customer
Asked: 2020-06-10
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. considering 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. 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 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 Testican 1 ELISA kit to have sensitivity of 10pg/ml, that means the minimum amount of Testican 1 that can be declared/interpreted as positive by the above standard is 10pg/ml.

Question
Q: can you tell me how to prepare cell lysates prepared for use in Picokine® ELISA kits?
Verified Customer
Verified customer
Asked: 2020-02-04
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 may impact immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Question
Q: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for measuring Testican 1 using the EK1848 Human Testican 1 Picokine® ELISA Kit?
H. Garcia
Verified customer
Asked: 2020-01-19
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 on priority basis collection when possible, or aliquot into single use volumes and store samples frozen. limit repetitive freeze-thaw cycles with the stored samples in order to limit protein degradation.

Question
Q: how much samples can be assayed in a Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2018-10-13
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 might differ by kit so please refer to each datasheet for details.

Question
Q: Are Boster Bio recombinant proteins and antibodies sterile?
Verified Customer
Verified customer
Asked: 2018-06-12
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 a must for an experiment, the material can be filtered through a 0.2 micron filter designed for use with biological fluids.

Question
Q: can you suggest the dilution ratio of serum samples for detection of Testican 1 in Human serum? 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: 2018-01-03
Answer
A: having little idea about 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 Testican 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: which procedure should I follow in order to thaw whole blood sample for Testican 1 ELISA after freezing?
Verified Customer
Verified customer
Asked: 2016-09-21
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 Testican 1 for a later time, you should let the blood clot in glass tubes and separate the serum to freeze for later analysis.
