Background of t-Plasminogen Activator/tPA
Plasminogen activator, tissue, also called PLAT or TPA is a serine protease. This gene encodes tissue-type plasminogen activator, a secreted serine protease which converts the proenzyme plasminogen to plasmin, a fibrinolytic enzyme. Tissue-type plasminogen activator is synthesized as a single chain which is cleaved by plasmin to a two chain disulfide linked protein. This gene was mapped to 8p11.21. This enzyme plays a role in cell migration and tissue remodeling. Increased enzymatic activity causes hyperfibrinolysis, which manifests as excessive bleeding; decreased activity leads to hypofibrinolysis which can result in thrombosis or embolism.

Question
Q: how are cell lysates prepared for use in Picokine® ELISA kits?
Verified Customer
Verified customer
Asked: 2019-10-14
Answer
A: for those Picokine® ELISAs where cell or tissue lysate is a validated sample type, sample preparation instructions for lysate can be found in the product insert. Components in lysate and lysis buffer can impact immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Question
Q: can you recommend the dilution ratio of serum samples for detection of tPA in Human urine? I am trying to measure a few analytes and it requires 100ul of diluted samples for each well. We have limited sample volumes so we like to dilute as much as possible.
Verified Customer
Verified customer
Asked: 2019-09-30
Answer
A: unable to understand 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 tPA 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 tPA ELISA after freezing?
Verified Customer
Verified customer
Asked: 2019-06-21
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 tPA for a later time, you should let the blood clot in glass tubes and collect the serum to freeze for later use.

Question
Does the kit also determine mouse tPA? Can it detect Alteplase in mouse blood? Keyword: applications, clinical
Verified Customer
Verified customer
Asked: 2019-02-08
Answer
No, it can't recognize mouse TPA. The standard in EK0897 is recombinant human PLAT(CHO, M1-P562). The kit can recognize the Alteplase in theory if the sequence is included. But it also depends on the constitution of the recombinant protein. Pilot assay is recommended first.

Question
Q: Are Boster Bio recombinant proteins and antibodies sterile?
P. Phillips
Verified customer
Asked: 2018-10-25
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: What is the optimal O.D. value for tPA ELISA kit? I performed your tPA 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 tPA even though the O.D. values are not very high?
W. Martinez
Verified customer
Asked: 2016-05-17
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 example mentioned, 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 tPA ELISA kit to have sensitivity of 10pg/ml, that means the minimum amount of tPA that can be declared/interpreted as positive by the above standard is 10pg/ml.

Question
Q: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for measurement tPA using the EK0897 Human tPA Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2014-06-05
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 on-stat 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.
