Background of
The green fluorescent protein (GFP) is a protein composed of 238 amino acid residues (26.9 kDa) that exhibits bright green fluorescence when exposed to light in the blue to ultraviolet range. Although many other marine organisms have similar green fluorescent proteins, GFP traditionally refers to the protein first isolated from the jellyfish Aequorea victoria. In cell and molecular biology, the GFP gene is frequently used as a reporter of expression. In modified forms it has been used to make biosensors, and many animals have been created that express GFP as a proof-of-concept that a gene can be expressed throughout a given organism. The GFP gene can be introduced into organisms and maintained in their genome through breeding, injection with a viral vector, or cell transformation. To date, the GFP gene has been introduced and expressed in many Bacteria, Yeast and other Fungi, fish (such as zebrafish), plant, fly, and mammalian cells, including human.

Intra Assay Consistency & Inter Assay Consistency
We measured random samples of GFP/Green fluorescent protein 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.

Question
Are there any additional recommendations for using EK1440 with mouse brain samples?
Verified customer
Asked: 2022-05-19
Answer
Our lab hasn't worked on tissue samples with the GFP/Green Fluorescent Protein ELISA Kit PicoKine® (EK1440). Endogenous biotin in tissue homogenates might introduce false positive signal. We recommend running 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. The background signal generated by endogenous biotin in the samples should be considered.

Question
Can EK1440 detect YFP/GFP in plants?
Verified customer
Asked: 2021-11-12
Answer
Our lab hasn't detected YFP/GFP in plants using the GFP/Green Fluorescent Protein ELISA Kit PicoKine® (EK1440). We are uncertain if the kit is able to detect YFP/GFP in plants. We suggest running a pilot test to see if it works. In theory, if the expression level of GFP in the samples falls in the assay range of the kit, the kit is able to detect the protein in the sample.

Question
Q: What is the optimal O.D. value for GFP ELISA kit? I used your GFP 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 GFP even though the O.D. values are not very high?
L. Collins
Verified customer
Asked: 2020-08-03
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. 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 proportion 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 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 GFP ELISA kit to have sensitivity of 10pg/ml, that means the minimum amount of GFP that can be declared/interpreted as positive by the above standard is 10pg/ml.

Question
Q: Can GFP ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
B. Wang
Verified customer
Asked: 2020-07-30
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 suitable 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 view 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.

Q: if the enzyme conjugated GFP 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 GFP antigen?

Asked: 2019-04-05
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.

Q: what is the protocol regarding preparation of cell lysates prepared for use in Picokine® ELISA kits?
Verified Customer
Verified customer
Asked: 2018-03-27
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.
