Background of IL-4
Interleukin-4 (IL-4), also knowns as a B-cell stimulatory factor1 (BSF1), is an immunomodulatory cytokine, which can inhibit the growth of tumour cells.1 The human cDNA contains a single open reading frame encoding a protein of 153 amino acids, including a putative signal peptide. IL-4 may act as an autocrine growth factor in pancreatic cancer cells and also give rise to the possibility that cancer-derived IL-4 may suppress cancer-directed immunosurveillance in vivo in addition to its growth-promoting effects, thereby facilitating pancreatic tumor growth and metastasis.1 The mouse and human genes and their protein products show structural and functional similarities. The human IL-4 gene, which occurs as a single copy in the haploid genome, is mapped on chromosome 5.2 The standard product used in this kit is recombinant human IL-4, consisting of 130 amino acids with the molecular mass of 14KDa.
Antibody Validation

Question
Will anti-IL4 antibody PA1424 work for WB with oocyte?
Verified Customer
Verified customer
Asked: 2019-11-18
Answer
According to the expression profile of oocyte, IL4 is highly expressed in oocyte. So, it is likely that anti-IL4 antibody PA1424 will work for WB with oocyte.

Question
We are currently using anti-IL4 antibody PA1424 for human tissue, and we are happy with the WB results. The species of reactivity given in the datasheet says human. Is it likely that the antibody can work on canine tissues as well?
Verified Customer
Verified customer
Asked: 2019-10-30
Answer
The anti-IL4 antibody (PA1424) has not been tested for cross reactivity specifically with canine tissues, though there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in canine you can get your next antibody for free. Please contact me if I can help you with anything.

Question
Can you help my question with product PA1424, anti-IL4 antibody. I was wondering if it would be possible to conjugate this antibody with biotin. I would need it to be without BSA or sodium azide. I am planning on using a buffer exchange of sodium azide with PBS only. Would there be problems for me to conjugate the antibody and store it in -20 degrees in small aliquots?
S. Jones
Verified customer
Asked: 2019-09-16
Answer
We suggest not storing this antibody with PBS buffer only in -20 degrees. If you want to store it in -20 degrees it is best to add some cryoprotectant like glycerol. If you want carrier free PA1424 anti-IL4 antibody, we can provide it to you in a special formula with trehalose and/or glycerol. These molecules will not interfere with conjugation chemistry and provide a good level of protection for the antibody from degradation. Please be sure to specify this in your purchase order.

Question
Does anti-IL4 antibody PA1424 work on goat WB with oocyte?
L. Miller
Verified customer
Asked: 2013-10-02
Answer
Our lab technicians have not validated anti-IL4 antibody PA1424 on goat. You can run a BLAST between goat and the immunogen sequence of anti-IL4 antibody PA1424 to see if they may cross-react. If the sequence homology is close, then you can perform a pilot test. Keep in mind that since we have not validated goat samples, this use of the antibody is not covered by our guarantee. However we have an innovator award program that if you test this antibody and show it works in goat oocyte in WB, you can get your next antibody for free.

Question
Does PA1424 anti-IL4 antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?
M. Evans
Verified customer
Asked: 2013-01-31
Answer
You can see on the product datasheet, PA1424 anti-IL4 antibody as been tested on WB. It is best to use PFA for fixation because it has better tissue penetration ability. PFA needs to be prepared fresh before use. Long term stored PFA turns into formalin, as the PFA molecules congregate and become formalin.
