Background of Semaphorin 3F
Semaphorin-3F is a protein that in humans is encoded by the SEMA3F gene. It is mapped to 9; 9 F1. The semaphorins are a family of proteins that are involved in signaling. All the family members have a secretion signal, a 500-amino acid sema domain, and 16 conserved cysteine residues. Sequence comparisons have grouped the secreted semaphorins into 3 general classes, all of which also have an immunoglobulin domain. The semaphorin 3 family, consisting of human semaphorins 3A-G, chicken collapsin, and mouse semaphorins 3A-G, all have a basic domain at the C terminus. Chicken collapsin contributes to path finding by axons during development by inhibiting extension of growth cones through an interaction with a collapsin response mediator protein of relative molecular mass 62K , a putative homolog of an axonal guidance associated UNC33 gene product. SEMA3F is a secreted member of the semaphorin III family.

7 Customer Q&As for Mouse SEMA3F/Semaphorin-3F ELISA Kit PicoKine®
Question
Q: Can Semaphorin 3F ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
L. Smith
Verified customer
Asked: 2019-08-23
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 a must. 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 assessd 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.

Question
Q: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for analysis Semaphorin 3F using the EK1734 Mouse Semaphorin 3F Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2019-05-15
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 repetitive freeze-thaw cycles with the stored samples to prevent protein degradation.

Question
Q: What is the optimal O.D. value for Semaphorin 3F ELISA kit? I used your Semaphorin 3F 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 Semaphorin 3F even though the O.D. values are not very high?
K. Patel
Verified customer
Asked: 2019-02-07
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 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 Semaphorin 3F ELISA kit to have sensitivity of 10pg/ml, that means the minimum amount of Semaphorin 3F that can be declared/interpreted as positive by the above standard is 10pg/ml.

Question
Q: how are cell lysates prepared for use in Picokine® ELISA kits?
Verified Customer
Verified customer
Asked: 2015-03-14
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.
