Background of Plexin B2
Plexin-B2 is a protein that in humans is encoded by the PLXNB2 gene. It is mapped to 7q34. Members of the B class of plexins, such as PLXNB2 are transmembrane receptors that participate in axon guidance and cell migration in response to semaphorins.

Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Rat Plexin B2/PLXNB2 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.

10 Customer Q&As for Rat Plexin B2/PLXNB2 ELISA Kit PicoKine®
Question
Q: which procedure should I follow in order to thaw whole blood sample for Plexin B2 ELISA after freezing?
H. Rodriguez
Verified customer
Asked: 2020-10-20
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 Plexin B2 for a later time, you should let the blood clot in glass tubes and collect the serum to freeze for later use.

Question
Q: can I use citrate plasma as samples in Rat Plexin B2 Picokine® ELISA Kit (Catalog # EK1883)?
Verified Customer
Verified customer
Asked: 2020-09-23
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can sequester metal ions from the functional domain of Plexin B2 causing degradation of its protein structure. Plexin B2 may be denatured as a result and may compromise the assay's measurements. The chilating sites could also be too close to the epitopes needed for detection and block the antigen antibody reaction. We have tested the Plexin B2 ELISA, treating samples with a number of anticoagulants and decided that heparin or EDTA can be used for treatment of blood/plasma samples. Do not use other anticoagulents when collecting samples.

Question
Q: we need your suggestion regarding the dilution ratio of serum samples for detection of Plexin B2 in Rat serum? I am trying to measure a few 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: 2019-08-13
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 Plexin B2 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: can you tell me how to prepare cell lysates prepared for use in Picokine® ELISA kits?
H. Collins
Verified customer
Asked: 2018-12-10
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 effect 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 Plexin B2 using the EK1883 Rat Plexin B2 Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2018-03-09
Answer
A: Boster Bio does not assess sample stability. Variations in sample collection, processing, and storage may alter 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 repeat freeze-thaw cycles with the stored samples in order to limit protein degradation.

Answered: 2018-03-09
Question
Q: if the enzyme conjugated Plexin B2 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 Plexin B2 antigen?
S. Taylor
Verified customer
Asked: 2018-01-07
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: Are Boster Bio recombinant proteins and antibodies sterile?
H. Smith
Verified customer
Asked: 2016-01-25
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 required for an experiment, the material can be filtered through a 0.2 micron filter designed for use with biological fluids.

Asked: 2015-07-23
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.
