Background of Oncostatin M/OSM
OSM (Oncostatin M) is a protein that in humans is encoded by the OSM gene. OSM is a pleiotropic cytokine that belongs to the interleukin 6 group of cytokines. The OSM gene is mapped on 22q12.2. Of these cytokines it most closely resembles leukemia inhibitory factor (LIF) in both structure and function. Treatment with recombinant OSM leads to the inhibition of proliferation and changes in cellular morphology of a number of tumor cell lines derived from a wide variety of tissue types. OSM signals through cell surface receptors that contain the protein gp130. The type I receptor is composed of gp130 and LIFR, the type II receptor is composed of gp130 and OSMR.

9 Customer Q&As for Mouse OSM/Oncostatin M ELISA Kit PicoKine®
Question
Q: what is the protocol regarding preparation of cell lysates prepared for use in Picokine® ELISA kits?
Verified Customer
Verified customer
Asked: 2019-12-18
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 can change immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Question
Q: which procedure should I follow in order to thaw whole blood sample for Oncostatin M ELISA after freezing?
Verified Customer
Verified customer
Asked: 2019-08-16
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 Oncostatin M for a later time, you should let the blood clot in glass tubes and collect the serum to freeze for later use.

Question
Q: What is the optimal O.D. value for Oncostatin M ELISA kit? I used your Oncostatin M 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 Oncostatin M even though the O.D. values are not very high?
Verified Customer
Verified customer
Asked: 2019-04-29
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. an important assessment should be is whether your sample O.D. values are statistically significantly higher than your blank values. in the above example, 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 converting 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 Oncostatin M ELISA kit to have sensitivity of 10pg/ml, that means the minimum amount of Oncostatin M that can be declared/interpreted as positive by the above standard is 10pg/ml.

Question
Q: Can Oncostatin M ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
Verified Customer
Verified customer
Asked: 2019-03-21
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 needed. 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.

Asked: 2017-11-11
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 vary slightly by kit so please refer to each datasheet for details.

Question
Q: is it okay to use citrate plasma as samples in Mouse Oncostatin M Picokine® ELISA Kit (Catalog # EK0479)?
Verified Customer
Verified customer
Asked: 2016-07-06
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can attach metal ions from the functional domain of Oncostatin M causing disruption of its protein structure. Oncostatin M 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 Oncostatin M 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: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for quantification Oncostatin M using the EK0479 Mouse Oncostatin M Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2016-02-18
Answer
A: Boster Bio does not evaluate sample stability. Variations in sample collection, processing, and storage may alter 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. avoid repetitive freeze-thaw cycles with the stored samples in order to limit protein degradation.

Question
Q: we need your recommendation regarding the dilution ratio of serum samples for detection of Oncostatin M in Mouse plasma? I am trying to measure a a number of analytes and it requires 100ul of diluted samples for each well. We have low serum volumes so we like to dilute as much as possible.
Verified Customer
Verified customer
Asked: 2014-08-28
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 Oncostatin M 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.
