Background of CD27/TNFRSF7

CD27 antigen, also called CD27 or TNFRSF7 is a tumor necrosis factor receptor. This gene is mapped to 12p13.31. The protein encoded by this gene is a member of the TNF-receptor superfamily. This receptor is required for generation and long-term maintenance of T cell immunity. It binds to ligand CD70, and plays a key role in regulating B-cell activation and immunoglobulin synthesis. This receptor transduces signals that lead to the activation of NF-kappaB and MAPK8/JNK. Adaptor proteins TRAF2 and TRAF5 have been shown to mediate the signaling process of this receptor. CD27-binding protein (SIVA), a proapoptotic protein, can bind to this receptor and is thought to play an important role in the apoptosis induced by this receptor.

6 Customer Q&As for Human TNFRSF7/CD27 ELISA Kit PicoKine®

Question

Q: can you tell me how to prepare cell lysates prepared for use in Picokine® ELISA kits?

W. Scott

Verified customer

Asked: 2020-07-23

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 effect immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Question

Q: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for measuring CD27 using the EK0698 Human CD27 Picokine® ELISA Kit?

L. Moore

Verified customer

Asked: 2019-04-20

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 on priority basis collection when possible, or aliquot into single use volumes and store samples frozen. avoid repeat freeze-thaw cycles with the stored samples to avoid protein degradation.

Question

Q: Can CD27 ELISA Kits be used with tissue homogenates (or other non-validated sample types)?

L. Miller

Verified customer

Asked: 2018-11-10

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 required. 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.

Question

Q: we need your recommendation regarding the dilution ratio of serum samples for detection of CD27 in Human serum? I am trying to measure a multiple analytes and it requires 100ul of diluted samples for each well. We have low serum quantitys so we like to dilute as much as possible.

T. Walker

Verified customer

Asked: 2018-08-21

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 CD27 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.
