We do not have data for camel samples tested with the human insulin ELISA, ab100578. However, insulin is well-conserved between the two species, so it is possible the ELISA will detect camel insulin.

To check the similarity between the two species, I used the camel UniProt database entry at the following link:

P01320 (INS_CAMDR) http://www.uniprot.org/uniprot/P01320

The pig insulin ELISA ab156515 will be a slightly better choice, since camel insulin is more similar to pig insulin than human.

Here are the percentage identity results of the alignments of camel insulin precursor with human and pig insulin.

93% w/ human insulin B chain http://www.uniprot.org/blast/?about=P01308[25-54]
90% w/ human insulin Achain http://www.uniprot.org/blast/?about=P01308[90-110]

97% w/ pig insulin B chain http://www.uniprot.org/blast/?about=P01315[25-54]
90% w/ pig insulin A chain http://www.uniprot.org/blast/?about=P01308[90-110]

Thanks for your enquiry.

The kit can be used within 1 year if the entire kit is stored unopened at -20 degrees C. After opening, please refer to the protocol booklet for component-specific storage instructions.

The general sample information for the Insulin Human ELISA Kit (ab100578) is a suggested dilution of normal serum/plasma: 2-10 fold (page 10 of the Protocol Booklet).
We however recommend testing different dilutions such as 1:2, 1:5, 1:10 to determine which one is the best for your particular sample.
Once the sample has been diluted, 100ul of sample should be added into appropriate wells and incubate for 2.5 hours at room temperature or over night at 4C with gentle shaking (remember to cover well the plate). For the following steps please follow the kit protocol at page 11 of the Protocol Booklet.

The antibodies used in this kit will recognize Insulin and Proinsulin. From the information which I have been able to gather on SwissProt regarding insulin (http://www.uniprot.org/uniprot/P01308) the insulin precuror is composed of a signal peptide, chains A, B and a C peptide. It seems that insulin is the heterodimer of chain A and chain B and that proinsulin contains chain A, B and peptide C. While I cannot be sure of whether the proinsulin is non functional it seems likely that this form could be compared to the functional heterodimer. If this is incorrect please let me know. Assuming that this is correct, then ab100578 will recognize both forms. I am sorry that I could not be more helpful, but I hope that the available literature in this area can provide some clarification. Please do not hesitate to contact us again with other needs or with any questions about our products.

Les anticorps utilisés dans le kit ELISA ab100578 sont les anticorps ab8304 comme anticorps de capture et ab20756 comme anticorps de détection. Ces deux anticorps sont testés et garantis chez le rat. Le kit lui-même n’a pas été testé chez le rat mais il y’a des chances que cela fonctionne. Si vous souhaitez le tester, je peux vous faire une offre de test.
