  • Product overview

    Abcam’s G-CSF Human ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human G-CSF in serum, plasma, and cell culture supernatants.

    This assay employs an antibody specific for Human G-CSF coated on a 96-well plate. Standards and samples are pipetted into the wells and G-CSF present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human G-CSF antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of G-CSF bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

    Get results in 90 minutes with Human G-CSF ELISA Kit (CSF3) (ab188390) from our SimpleStep ELISA® range.

    Granulocyte Colony Stimulating Factor (G-CSF) a cytokine that controls the production, differentiation, and function of granulocytes. It is a potent stimulator of bone marrow cells especially those of neutrophil lineage. In addition, G-CSF can enhance the survival and activate the immunological functions of mature neutrophils. Recombinant human G-CSF has been developed by pharmaceutical companies, and since the late 1980's, multiple clinical trials have explored its efficacy in a variety of conditions.

We have not tested the GCSF ELISA kit with Cynomolgus monkey serum. However, when looking at the human GCSF sequence our kit recognizes and testing the cross-reactivity to the Cynomolgus sequence, there are a number of predicted matches, including granulocyte colony-stimulating factor (isoforms X1-4), with which it has 94% homology. Thus, it is likely that the kit will work with Cynomologus serum. Especially since we have a 90 day 100% risk-free policy for ELISAs, there is no risk in this case to try it.

Please keep in mind though that there are a number of other predicted matches (other than GCSF) with varying homology that it may cross-react with and there is not a 100% sequence match. So you will have to consider this when interpreting any results.

The standard recombinant protein of ab100524 was expressed in E.coli.

The standard we use for this kit (ab100524) is recombinant human G-CSF: 18.7 kDa protein; 174 amino acid residues. We have not tested this kit with a met-GCSF, but the following amino acid sequence of the recombinant standard used should help the customer determine whether or not the antibody pairs used will recognize the met-GCSF as well:


If your customer has the sequence of the methionyl GCSF, we could compare the sequences to see whether this kit is likely to work on methionyl GCSF.

Thank you for contacting us.

Serum can be stored at -80C for a month, this will be having minimal affect on the assay.

The following publication will help understanding the affect of temperature on different serum protein.


I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Thank you for your reply.

The strips come with a rack where the single strips can be inserted.

This rack will fit all standard plate readers.

I am sorry, I cannot check if this is also true for your plate reader. Please ask the supplier of the instrument.

I hope this information is helpful and wish you good luck with experiments.

Thank you for your inquiry.

I can confirm that with ab100524 it is not necessary to use the whole plate at one time.

The plate comes in convenient 12 strips x 8 wells.

Please follow the instruction of the protocol when storing opened plate and solutions:


ab100524 may be stored for up to 6 months at 2 to 8°C from the

date of shipment. Standard (recombinant protein) should be stored

at -20°C or -80°C (recommended at –80°C) after reconstitution.

Opened Microplate Wells or reagents may be store for up to 1 month

at 2 to 8°C. Return unused wells to the pouch containing desiccant

pack, reseal along entire edge. Note: the kit can be used within one

year if the whole kit is stored at -20°C. Avoid repeated freeze-thaw


I hope this information is helpful and wish you good luck with your experiments.

Thank you for contacting Abcam.

We still have not tested whether the kit can be used to quantitate PEGfilgrastim, therefore the original response, "to spike in pegylated G-CSF and see" is still the only option for answering this question.

If there is anything else I can help you with, please let me know.

Thank you for your inquiry.  That is a good question.  I reviewed our testing records on ab100524 but unfortunately I was not able to find any data about pegylated G-CSF.  Therefore we don’t know if this kit will also detect the pegylated form.  The only way to know would be to spike in pegylated G-CSF and see.   I wish I could be of more help, but please let us know if you have any other questions.
