Background of JAM-A

Junctional adhesion molecule A (JAM-A) is a protein that in humans is encoded by the F11R gene. It is mapped to 1q23.3. This gene is an immunoglobulin-like molecule that colocalizes with tight junctions in endothelium and epithelium and is also found on blood leukocytes and platelets. JAM-A plays an important role in the regulation of tight junction assembly in epithelia. In addition, it can act as a receptor for reovirus, a ligand for the integrin LFA1, involved in leukocyte transmigration, and a platelet receptor. JAM-A has a nonredundant role in controlling DC motility, trafficking to lymph nodes, and activation of specific immunity.

Question

Q: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for measurement JAM-A using the EK1349 Human JAM-A Picokine® ELISA Kit?

D. Liu

Verified customer

Asked: 2020-07-04

Answer

A: Boster Bio does not evaluate 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 in order to limit protein degradation.

Question

Q: how can I thaw whole blood sample for JAM-A ELISA after freezing?

K. Dayal

Verified customer

Asked: 2020-05-25

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 JAM-A for a later time, you should let the blood clot in glass tubes and collect the serum to freeze for later use.

Question

Q: Are Boster Bio recombinant proteins and antibodies sterile?

Verified Customer

Verified customer

Asked: 2020-03-30

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: What is the optimal O.D. value for JAM-A ELISA kit? I used your JAM-A 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 JAM-A even though the O.D. values are not very high?

S. Zhou

Verified customer

Asked: 2018-02-04

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. what you should focus on is whether your sample O.D. values are statistically significantly higher than your blank values. regarding your protocol, 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 proportion 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 JAM-A ELISA kit to have sensitivity of 10pg/ml, that means the minimum amount of JAM-A that can be declared/interpreted as positive by the above standard is 10pg/ml.

Question

Could you let me know if EK1349 will work with human brain tissue homogenates (homogenates are in a 1% NP-40 lysis buffer)?

Verified Customer

Verified customer

Asked: 2013-01-22

Answer

Our lab hasn't woked on human brain tissue samples using EK1349. Endogenous biotin in tissue homogenates might introduce false positive signal. We recommend the customer to run a pilot test as described below to confirm the affect of endogeous biotin first. Add tissue homogenates into the wells and then add ABC abd TMB without adding any biotinylated detection antibody to see if any signal will be observed. If no signal is produced, the customer can work on the tissue sample by using the kit.
