On this page we present all of the data we have available for our D. pteronyssinus house dust mite extract and the D. farinae HDM extract. We have compared our available batches with each other and we have also performed a stability study over the last 5 years. Based on this information, you can make a substantiated choice for a suitable extract. This means you are assured of stable and reliable material for your research. 

Below you will find various tables containing the data of our HDM batches. It may be that the tables are not legible, in that case you can also download the complete report in .pdf via this link or the following button. More questions? Let us know!

Batches D. pteronyssinus extract

 

In the table below we have collected the available data from our D. pteronyssinus extract. This data can also be found on the certificates of analysis which we deliver with our products. The first 2 numbers of the charge number stands for the year of production, for example 20B12 was produced in 2020 and 15G10 was produced in 2015. 

Batches D. farinae extract

In the table below we have collected the available data from our D. farinae extract. This data can also be found on the certificates of analysis which we deliver with our products. The first 2 numbers of the charge number stands for the year of production, for example 19K19 was produced in 2019 and 15G06 was produced in 2015.

 Batches low endotoxin HDM extracts

 In the table below we have collected the available data from our D. pteronyssinus and D. farinae low endotoxin extracts. This data can also be found on the certificates of analysis which we deliver with our products. 

  • Batches 19A17 and 18K01 are the D. pteronyssinus low-endo extracts
  • Batch 19A18 is the D. farinae low-endo extract.

Stability study D. pteronyssinus extracts

We have performed stability studies to see if our D. pteronyssinus extracts  are still stable. We collected data over the course of 5 years and the conclusion is that the HDM extracts are still within the limits although there is a change. The limits are based on the European Pharmacopoeia Monography of allergens (01/2010:1063). Because we have multiple large batches which are produced in 2015 it is important for you to know that these batches are still reliable.

In the table below you can find the stability for 4 of our D. pteronyssinus (02.01.85) batches. More information about the stability of our extracts can be found on this page.

 Stability study D. farinae extracts

 We have performed stability studies to see if our D. farinae extracts are still stable. We collected data over the course of 5 years and the conclusion is that the HDM extracts are still within the limits although there is a change. In the table below you can find the stability for 3 of our D. farinae (02.02.85) batches.
