Background of B7-1/CD80
The protein CD80 (Cluster of Differentiation 80) is a molecule found on activated B cells and monocytes which provides a costimulatory signal necessary for T cell activation and survival. It is also known as B7-1. The cDNA for B7-1 predicts a type I membrane protein, i.e., one synthesized with a signal peptide that is cleaved upon translocation across the endoplasmic membrane. The protein is predicted to contain 2 extracellular domains structurally similar to those of Ig, a hydrophobic transmembrane region, and a short cytoplasmic domain.The CD80 and CD86 genes encode B7-1 and B7-2, respectively, which are structurally similar members of the immunoglobulin superfamily expressed on a variety of hematopoietic cell types. B7-1 and B7-2 provide a costimulatory signal to T cells by interacting with CD28 and CTLA4.

Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Rat B7-1/CD80 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
Q: Are Boster Bio recombinant proteins and antibodies sterile?
Verified Customer
Verified customer
Asked: 2020-06-15
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.

Question
Q: how can I thaw whole blood sample for CD80 ELISA after freezing?
M. Kapoor
Verified customer
Asked: 2019-02-11
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 CD80 for a later time, you should let the blood clot in glass tubes and separate the serum to freeze for later analysis.

Question
Q: how many samples can be assayed in a Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2019-01-31
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.

Question
Q: if the enzyme conjugated CD80 antibodies are mixed with the substrate, will that convert the substrate into the enzymatic reaction product? Or the enzyme function is only activated when the antibody is attached with the CD80 antigen?
C. Dhawan
Verified customer
Asked: 2017-08-16
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: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for measuring CD80 using the EK0709 Rat CD80 Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2017-07-25
Answer
A: Boster Bio does not evaluate sample stability. Variations in sample collection, processing, and storage may affect the stabilityof samples. It is recommend to assay sample on-stat collection when possible, or aliquot into single use volumes and store samples frozen. avoid repetitive freeze-thaw cycles with the stored samples to limit protein degradation.
