Recommended Sample Dilution Ratios

According to our internal validation assays using this ELISA kit, to detect CXCL8/IL-8, Dilution ratio of 1:1, concentration in serum is target in serum is below detection limit..

Some articles we found to cite concentrations of CXCL8/IL-8 in samples: 15529589 (Pubmed IDs).

Intra Assay Consistency & Inter Assay Consistency

We measured random samples of Human IL-8/Interleukin-8/CXCL8 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.

Our lab hasn't worked on tissue homogenate samples using the Human IL-8 ELISA Kit PicoKine™ (EK0413). Endogenous biotin in tissue homogenates might introduce false positive signals. We recommend the customer to run a pilot test as described below to confirm the effect of endogenous 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. Please see the following suggested protocol. Procedure for Lysis of Tissues Note: Pre-chill an appropriate volume of IP Lysis Buffer at 4 ˚C. If desired, add protease inhibitor and phosphatase inhibitor to the lysis buffer immediately before use. 1.Place the fresh tissue into chilled PBS and rinse several times. Mince the tissue into small pieces. 2.Add ice cold IP lysis buffer(Cat#AR0107) to the tissue at 10:1(v/w). (i.e., Add 1ml lysis buffer to 0.1g tissue sample.) Use a larger volume of reagent if lysis is insufficient. Use a smaller volume of reagent if a more concentrated protein extract is required. 3.Homogenize for several minutes with a glass homogenizer at high speed until no tissue chunks remain. 4.Incubate on ice for 10 minutes. 5.Centrifuge at ~13000 x g for 10 minutes at 4°C. 6.Transfer supernatant to a new tube for further analysis.

Q: what is the protocol regarding preparation of cell lysates prepared for use in Picokine® ELISA kits?

Verified Customer

Asked: 2020-05-03


A: for those Picokine® ELISAs where cell or tissue lysate is a validated sample type, sample preparation instructions for lysate can be found 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.

Q: is it okay to use citrate plasma as samples in Human CXCL8 Picokine® ELISA Kit (Catalog # EK0413)?

Verified Customer

Asked: 2020-04-18


A: Chelating agents such as EDTA, Heparin and Citrate can bind metal ions from the functional domain of CXCL8 causing degradation of its protein structure. CXCL8 may be denatured as a result and may compromise the assay's measurements. The chilating sites could also be too close to the epitopes a must for detection and block the antigen antibody reaction. We have tested the CXCL8 ELISA, treating samples with various anticoagulants and decided that heparin, EDTA or citrate can be used for treatment of blood/plasma samples. Do not use other anticoagulents when collecting samples.

Can EK0413 be used to run the Enzyme-Linked Immunosorbent Assay (ELISA) test for Human salivary obtained from gum?

Verified customer

Asked: 2019-10-20


Our lab hasn't tested the Human IL-8 ELISA Kit PicoKine EK0413 on human salivary. It is uncertain if the kits are able to work on human salivary. We suggest to run a pilot test if you want to try. In theory, if the expression level of the target protein in the salivary falls in the assay range of the kit, the kit should be able to detect the protein in the sample.

Q: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for quantification CXCL8 using the EK0413 Human CXCL8 Picokine® ELISA Kit?

Asked: 2019-08-31


A: Boster Bio does not assess sample stability. Variations in sample collection, processing, and storage may change the stabilityof samples. It is recommend to assay sample immediately 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.

I used your product EK0413 for urine samples, should it be diluted with the standard diluent human serum? Or standard diluent buffer?

Verified Customer

Verified customer

Asked: 2018-02-01


The EK0413 kit is suitable to use with all human body fluids, however urine samples should be diluted in standard buffer containing PBS BSA. We suggest to start the dilution at 1:1(50 uL of samples and 50 uL of diluent).
