Do I have enough MIX/EIA Diluent to run ELISA with all my 40 samples at 10,000x?

Assaypro provides enough Diluent to do 1,000,000-fold dilutions. We recommend that customers prepare samples with serial dilutions.
  • Diluent Concentrate 10x (30 ml) is provided
  • Dilute 1:10 to get 300 ml of 1x ready to use Diluent
  • Prepare 10,000x serial dilutions with 1xDiluent. See guidelines for diluting samples below.

Guidelines for Dilutions of 1:100 or Greater

1:100
1:10000

A) 4 ul sample: 396 µl buffer
= 100 fold dilution

Assuming the needed volume is less than or equal to 400 µl.

A) 4 µl sample : 396 µl buffer (100x)
B) 4 µl of A : 396 µl buffer (100x)
= 10000 fold dilution

Assuming the needed volume is less than or equal to 400 µl.

1:1000
1:100000

A) 4 µl sample : 396 µl buffer (100x)
B) 24 µl of A : 216 µl buffer (10x)
= 1000 fold dilution

Assuming the needed volume is less than or equal to 240 µl.

A) 4 µl sample : 396 µl buffer (100x)
B) 4 µl of A : 396 µl buffer (100x)
C) 24 µl of B : 216 µl buffer (10x)
= 100000 fold dilution

Assuming the needed volume is less than or equal to 240 µl.
